Planet Money pal Charlie Wheelan has a nice piece in the WSJ under the headline "10 Things Your Commencement Speaker Won't Tell You."
Here's one that rings true:
Some of your worst days lie ahead. Graduation is a happy day. But my job is to tell you that if you are going to do anything worthwhile, you will face periods of grinding self-doubt and failure. Be prepared to work through them. I'll spare you my personal details, other than to say that one year after college graduation I had no job, less than $500 in assets, and I was living with an elderly retired couple. The only difference between when I graduated and today is that now no one can afford to retire.
Other pearls include "Your parents don't want what's best for you," and "Don't try to be great." Read the whole thing here.
