Becoming a scientist, economist, historian, or any expert in a certain field requires much more than just reading many books on the subject. While reading and absorbing knowledge is an important part of learning, it is equally crucial to engage actively with the subject matter, which could mean different things for different fields. Here are some general steps: Education and Knowledge: Start by gaining a solid foundation in your chosen field through formal education and self-study. This often involves reading textbooks, attending lectures, and educating oneself about the latest research and developments in the field. Observation and Critical Thinking: For all these professions, a key skill is the ability to observe patterns, analyze data, and derive meaningful conclusions. It involves looking at information from various angles and using analytical skills to understand complex issues. Practical Application and Experiments: Reading and learning about theories is just one part of it. One must also apply this knowledge in practical contexts, conduct experiments (in fields like science), or analyze historical events (in history) or economic data (in economics).
