Leadership means making tough decisions today that will benefit everyone tomorrow.

I think it is often easier to make progress on mega-ambitious dreams. Since no one else is crazy enough to do it, you have little competition. In fact, there are so few people this crazy that I feel like I know them all by first name.

荒野不会奖励最强或最快的人。它会奖励最适应的人。

Stay hungry for knowledge, and you’ll never run out of opportunities.
