I hope that in this year to come, you make mistakes. Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You're doing things you've never done before, and more importantly, you're doing something.

虽然殴打同学的行为不能通融，但我知道友情是值得捍卫的。

成功不是要成为最好的，而是要变得比昨天更好。

——在黄埔军校开学礼演说，1924年6月16日

Have you given any thought to your future？

Your time is limited, so don’t waste it living someone else’s life.
