仰不愧于天,俯不怍于人。
人活着,就应该坦坦荡荡,明明白白,无所愧疚。
I have always preferred working on concrete problems rather than abstract theories.
What's terrible is to pretend that second-rate is first-rate. To pretend that you don't need love when you do; or you like your work when you know quite well you're capable of better.
勇气不是没有恐惧,而是尽管恐惧仍选择行动。
