The twelve fastest ways to develop a sharp mind:

1. Active output rather than passive input: deepen understanding through explanations, writing, and other methods to promote knowledge absorption.
2. Deliberately ask "Why": continuously trace the essence of problems to avoid staying on the surface.
3. Build a dedicated knowledge system: connect scattered knowledge to form a structured understanding.
4. Cross-disciplinary learning and breaking stereotypes: borrow thinking methods from different fields to spark new ideas.
5. Review and reflect, turning experience into wisdom: regularly summarize to extract reusable methods and patterns.
6. Learn and work with questions in mind: clarify core issues first to improve learning efficiency.
7. High-quality, in-depth discussions: expand perspectives and optimize thinking through deep conversations.
8. Deliberately do challenging tasks to train the brain: step out of comfort zones to enhance cognitive abilities.
9. Allocate time for independent thinking: give your brain space daily to organize information and consolidate ideas.
10. Break down excellent cases and replicate their logic: learn the thought processes behind success.
11. Engage in moderate brain-intensive training: such as reading, problem-solving, reasoning, etc., to strengthen attention and logic.
12. Learn to think in reverse: view problems from different angles to cultivate diverse perspectives.
