How many times must a man look up Before he can see the sky？

The work of art is a fragment of the cosmos.

Life is a series of moments, some good, some bad, but all important.

If you're not stubborn， you'll give up on experiments too soon. And if you're not flexible， you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

唯一的出路是向内走。

In the end, we will remember not the words of our enemies, but the silence of our friends.
