成功不是终点，失败也非致命，重要的是继续前进的勇气。
"Success is not final, failure is not fatal: It is the courage to continue that counts."
成功的真正标准是我们对周围社区的影响。
Separate the processes of creation from improving. You can’t write and edit， or sculpt and polish， or make and analyze at the same time. If you do， the editor stops the creator. While you invent， don’t select. While you sketch， don’t inspect. While you write the first draft， don’t reflect. At the start， the creator mind must be unleashed from judgement.
Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
