To become a scientist, economist, or historian, one needs more than just reading books. While reading provides foundational knowledge, real expertise comes through observation, inquiry, and hands-on work. In science, this involves forming hypotheses, conducting experiments, analyzing data, and drawing conclusions. For an economist, it could mean studying market behavior, analyzing trends, and understanding economic impact. Historians examine primary sources and try to interpret historical events critically. All fields require thinking deeply, asking original questions, and searching for evidence-based answers. Thus, becoming an expert in any field demands a combination of curiosity, analysis, practical experience, and a desire to explore beyond textbooks.
