To do mathematics is to explore a universe of ideas, where the only limit is your imagination.

I think the key to success is to be passionate about what you're doing.

"The most important thing is to stay passionate."

The universe constantly surprises us, and that’s what makes science so exciting.

If you’re not failing occasionally, you’re not pushing hard enough.

You can't go back and change the beginning, but you can start where you are and change the ending.
