31 Interesting Subjects and Topics to Learn About

Introduction to This List of Interesting Subjects to Learn About

Here are 31 interesting subjects and topics to learn about, from AI automation and psychology to history and economics. Each entry says what the subject is and why it is worth your time.

Ten of them can also pay: people with expertise in fields like medicine, finance, science, coding and teaching are hired to train AI models, and those entries link to open roles. To learn how to study any of them, jump to How to Learn Any Subject, which covers learning styles and the study methods research supports.

1. AI Automations

AI automation means using AI models and automation software to run tasks people used to do by hand, like sorting email or moving data between apps. IBM describes intelligent automation as a way to simplify processes built on manual tasks, so learning it lets you clear your own busywork or build automations for other businesses.

Software engineers and other coders get paid to train AI models. See open coding roles and coding pay rates.

2. Online Teaching Jobs

Online teaching refers to the practice of educating students remotely through digital platforms. It encompasses a variety of methods including live video classes, pre-recorded sessions, interactive quizzes, and forums. Online teachers may also utilize tools to spot AI-created work to combat a lack of supervision in person. This approach to education provides flexible learning opportunities, accessible resources, and a wide array of subjects that cater to learners worldwide. Online teaching requires effective communication tools, engaging content delivery, and strategies for virtual classroom management.

Online teaching is worth learning if you like explaining things. Teachers are also hired to train AI models, and our AI training jobs for teachers page shows the work and who gets hired. See open teaching roles.

3. Digital Nomad

A digital nomad is someone who works remotely while traveling, using a laptop and an internet connection to do the job from anywhere. Learning how nomads choose where to live and find remote work is a practical first step toward a location-independent career.

4. Side Hustles

A side hustle is work that brings in extra money beyond your regular job. Studying side hustles shows you which ones fit your skills and hours, and some, like freelancing, grow into a small business.

5. Personal Development

Personal development covers the activities that build your capabilities and potential, from new skills to better habits. People study it to improve their quality of life and to reach goals they have set for themselves.

6. Productivity

Productivity as a subject is mostly time management: planning and consciously controlling how much time you spend on each activity. Learning it helps you get more done in the hours you already have.

7. Motivation & Inspiration

Motivation is the internal state that pushes people toward goal-directed behavior. Psychologists link it to results at school, at work and in sport, so understanding it helps you keep going on long projects.

8. Communication Skills

Communication is the passing of information from one person to another, through speech, writing, body language and listening. Researchers count communicative competence as a key factor in whether people reach their goals, so it repays practice in every job and relationship.

9. Biography & Memoir

A biography is a detailed account of a person's life, while a memoir is nonfiction written from the author's own memories. Reading both lets you learn history, careers and hard decisions through one person's story.

10. Religion & Spirituality

Religion covers the shared systems of belief, behavior and practice that shape cultures. Spirituality centers on the deepest values and meanings people live by, and studying both helps you understand the beliefs of the people around you.

11. Philosophy

Philosophy, literally “love of wisdom”, is the systematic study of basic questions about existence, knowledge, values and reason. Its main branches are epistemology, ethics, logic and metaphysics, and studying them trains you to build an argument and test one.

12. Creativity

Creativity is the ability to come up with new and valuable ideas or works. It runs through the arts, education and problem solving, so creative techniques help in almost any field.

Designers and other creative professionals get paid to train AI models. See open design and creative roles.

13. Education

Education is the passing on of knowledge and skills, along with the development of character. Studying how education works helps you teach, tutor or simply learn faster yourself.

Teachers get paid to train AI models. See open teaching roles.

14. Psychology

Psychology is the scientific study of the mind and behavior. It is used well beyond therapy, in workplaces and organizations too, so it helps you understand yourself and the people you work with.

15. Mindfulness & Happiness

Mindfulness means intentionally keeping a moment-by-moment awareness of what you are experiencing. Positive psychology, the science behind happiness research, studies the conditions that lead to positive psychological states, which makes the two a natural pair if you want to understand well-being.

16. Health & Nutrition

Nutrition science studies how the body takes in and uses food. It links nutrients to growth, health and disease, so the basics help you read food labels and health news with a sharper eye.

Doctors, nurses, pharmacists and other clinicians get paid to train AI models. See open medical roles and medical pay rates.

17. Career & Success

Career development is the process of moving your working life forward through choices about skills, roles and long-term learning. Studying it helps you plan your next move instead of drifting into one.

18. Management & Leadership

Management is the running of organizations, and leadership is the ability to influence or guide a person, a team or a whole company. Both matter as soon as you run a project, a shift or a small business.

Consultants and operations specialists get paid to train AI models. See open consulting and operations roles and consulting pay rates.

19. Entrepreneurship

Entrepreneurship is the creation of economic value, usually by starting and running a new business. It has been called a major driver of economic growth, and learning it teaches planning, selling and managing risk in one subject.

20. Marketing & Sales

Marketing is the work of winning, satisfying and keeping customers, and sales is the deal itself, where a seller passes ownership of a product to a buyer. Every business needs both, so these skills are useful whether you work for someone else or for yourself.

Marketing and sales professionals get paid to train AI models. See open marketing and sales roles.

21. Corporate Culture

Corporate culture, also called organizational culture, is the set of shared values and behaviors inside a company. Companies use it to coordinate very different teams, and knowing how it works helps you judge an employer before you join.

22. Science

Science builds and organizes knowledge as testable explanations about the world. It splits into the natural sciences, which study the physical world, and the social sciences, which study people, and learning how it works helps you judge the claims you hear every day.

Scientists get paid to train AI models. See open science roles and science pay rates.

23. Technology & the Future

Technology is the use of knowledge to reach practical goals, and its advances have changed society again and again. Futures studies looks ahead, using scenarios to map possible futures, which helps you plan a career around what is coming.

Engineers get paid to train AI models. See open engineering roles and engineering pay rates.

24. Nature & the Environment

Ecology studies how living things interact with each other and with their environment. It feeds directly into conservation and the management of natural resources, so it is the place to start if you care about the planet.

25. Love & Relationships

An interpersonal relationship is a connection between two or more people, from friendship to marriage. Researchers study relationships with tools from psychology, sociology and the other social sciences, and what they found can help you understand your own.

26. Parenting

Parenting is the work of supporting a child's physical, emotional, social and educational development. Parenting skills help guide children into healthy adulthood, which makes this subject worth studying before or after a child arrives.

27. Society & Culture

Sociology is the scientific study of human society, and anthropology studies humanity across biology and culture. Together they explain social class, social mobility and why customs differ from one place to the next.

28. History

History is the systematic study of the past, mostly the human past. Historians rebuild events from primary and secondary sources, and learning their methods helps you check the stories you are told about the past.

29. Money & Investments

Personal finance is how a person or a family budgets, saves and spends, including credit scores, income taxes and retirement funds. Investing means putting resources into something expected to gain value over time, and learning both helps you make better decisions with your own money.

Accountants and finance professionals get paid to train AI models. See open finance roles and finance pay rates.

30. Politics

Political science is the study of politics: systems of government and how power is won and used. Learning it helps you read the news, follow policy debates and vote with more context.

31. Economics

Economics studies how goods and services are produced, distributed and consumed. Economic analysis is used in business, finance, health care and government, so it explains a lot of everyday life, from prices to wages.

How to Learn Any Subject

The study methods with the strongest evidence are practice testing and spacing your study over several days. Matching lessons to your learning style has much weaker support, so treat your style as a preference and choose methods by the evidence.

What Are Learning Styles?

A learning style is the idea that each person learns best in one mode, such as words, pictures or speech. The VARK model is a questionnaire that sorts learning preferences into four types:

• Visual learners prefer maps, diagrams, charts, graphs and flow charts.
• Aural learners prefer lectures, group discussions, radio and podcasts.
• Read/write learners prefer reading and writing in all its forms.
• Kinesthetic learners prefer examples, case studies, demonstrations, simulations and practical applications.

Are Learning Styles Real?

Preferences are real, but the payoff from teaching to them is small. A 2008 review by Pashler, McDaniel, Rohrer and Bjork found plenty of evidence that people state preferences for how they take in information.

The same review found virtually no evidence for the meshing idea, that teaching in your preferred style helps you learn more, and several well-designed studies contradicted it.

A 2024 meta-analysis of 21 studies by Clinton-Lisell and Litzinger found a small benefit from matching. Only about a quarter of the outcomes showed the pattern the theory predicts, and the authors judged the benefit too small and too infrequent to justify widespread use.

Learning Strategies That Work

A 2013 review by Dunlosky and colleagues rated 10 common study techniques. Two came out on top, three were promising, and five were rated low:

• Practice testing, also called retrieval practice, means quizzing yourself from memory with flashcards, past questions or a blank page. In a 2006 study by Roediger and Karpicke, students who took recall tests remembered more two days and a week later than students who reread, even though rereading made them feel more confident.
• Spaced practice means spreading your sessions over days instead of cramming. A 2006 meta-analysis of 317 experiments found that the best gap between sessions grows the longer you need to remember the material.
• Interleaving means mixing different kinds of problems in one session. It was rated promising, with less evidence so far.
• Elaborative interrogation and self-explanation mean asking yourself why a fact is true and explaining each step in your own words. Both were rated promising.
• The five rated low were summarizing, highlighting, the keyword mnemonic, picturing text as images, and rereading. The review suggests practice testing in place of rereading.

A Simple Plan for Self-Directed Learning

Self-directed learning, or self-study, means learning a subject without a teacher guiding you. A plan built on the methods above:

1. Pick one subject from the list and one good book, course or set of notes.
2. After each session, close the material and write down or say what you remember.
3. Review on a spaced schedule, for example the next day, a few days later and a week later.
4. Mix topics or problem types once you know the basics.
5. Explain what you learned to someone else, or to yourself, in plain words.
