真相是，过去是我们所拥有的一切。我们无法改变它，但我们可以从中学习。

The best way to measure how much you've grown isn't by inches or the number of laps you can now run around the track, or even your grade point average - though those things are important, to be sure.It's what you've done with your time, how you've chosen to spend your days, and whom you've touched this year. That, to me, is the greatest measure of success.

"It is not the strength of the body that counts, but the strength of the spirit."

不要只销售产品，要销售价值观和愿景。
