生活中唯一真正的失败是不忠于自己所知道的最好的东西。

【译文】如果不明事理，那么动就不知道往哪里去;如果不动，那么即使明白事理也没有用处。

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.
