"我研究自己甚于研究其他任何学科，那就是我的形而上学，那就是我的物理学。"

Simplified Meaning:

The person who said this is talking about the importance of understanding themselves deeply. Instead of studying far-off topics or abstract ideas, they focus on learning about their own thoughts, feelings, and actions. Think of it like this: if a student spends more time trying to understand their own strengths and weaknesses rather than just memorizing facts from textbooks, they might find better ways to succeed in school and life. For example, by recognizing that they learn best in the early morning, they can schedule their hard tasks then. This approach can help anyone because knowing yourself well makes it easier to make good choices, solve problems, and improve where needed. So, spending time to reflect on and understand oneself can lead to personal growth and success in many areas of life.
