All you can decide is what you think now, and you need to be prepared to keep making revisions. Because let me be clear. I'm not trying to persuade you all to become writers or musicians. Being a doctor or a lawyer, a scientist or an engineer or an economist—these are all valid and admirable choices. All I'm saying is that you need to think about it, and think about it hard. All I'm asking is that you make your choices for the right reasons. All I'm urging is that you recognize and embrace your moral freedom.

And most of all, don't play it safe. Resist the seductions of the cowardly values our society has come to prize so highly: comfort, convenience, security, predictability, control. These, too, are nets. Above all, resist the fear of failure. Yes, you will make mistakes. But they will be your mistakes, not someone else's. And you will survive them, and you will know yourself better for having made them, and you will be a fuller and a stronger person.

It's been said—and I'm not sure I agree with this, but it's an idea that's worth taking seriously—that you guys belong to a "postemotional" generation. That you prefer to avoid messy and turbulent and powerful feelings. But I say, don't shy away from the challenging parts of yourself. Don't deny the desires and curiosities, the doubts and dissatisfactions, the joy and the darkness, that might knock you off the path that you have set for yourself. College is just beginning for you, adulthood is just beginning. Open yourself to the possibilities they represent. The world is much larger than you can imagine right now. Which means, you are much larger than you can imagine.
