The most important thing in science is not to be afraid to ask questions.

最好的数学家是那些不怕冒险的人。

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.

I think the best thing you can do is to be true to yourself.
