I believe it's important to have a passion for what you do. If you don't have a passion, you won't have the energy to keep going when things get tough.

The people who are crazy enough to think they can change the world are the ones who do.

宇宙不仅比我们想象的更奇怪，它比我们能想象的还要奇怪。

Happiness is not something ready made. It comes from your own actions.
