我不会让挫折阻止我，它们让我更强大。

I've been waiting more than 30 years to say this: "Dad, I always told you I'd come back and get my degree." I want to thank Harvard for this timely honor. I'll be changing my job next year…and it will be nice to finally have a college degree on my resume.

The future isn't written in the stars. There are no guarantees. So claim your adulthood. Be intentional. Get to work. Pick your family. Do the math. Make your own certainty. Don't be defined by what you didn't know or didn't do.

我们对未来持乐观态度，但我们知道仅靠乐观是不够的。
