我不相信后悔。

A mathematician is a device for turning coffee into theorems.

Here's an insight that I've had about success: You can't be successful at everything. We hear a lot of talk about work-life balance. Nonsense. You can't have it all. You can't. So any vision of success has to admit what it's losing out on, where the element of loss is. And I think any wise life will accept, as I say, that there is going to be an element where we're not succeeding.

The reality is: sometimes you lose. And you're never too good to lose. You're never too big to lose. You're never too smart to lose. It happens.

The study of mathematics is the indispensable basis for all intellectual and spiritual progress.

Anything you say before the word “but” does not count.
