I don't regret my past; I just regret the time I wasted on the wrong people.

The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease.

I don’t have time to worry about something as trivial as what I look like.

Your brain is like a muscle; the more you use it, the stronger it gets.

创新是唯一的取胜之道。

成功不是幸福的关键。幸福是成功的关键。如果你热爱你所做的事，你就会成功。
