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.

The opportunity does not go hand in hand, so when they come, you’d better hold them.
