Amy Poehler's Harvard graduation speech
Some nice thoughts:
You can't do it alone; be open to collaboration, other people's ideas are often better than your own. Find a group of people who challenge and inspire you, and it will change your life. No one is here today because they did it on their own, you are all here today because someone gave you strength, helped you, held you in the palm of their hand. They helped you get here and that should make you feel less alone and less scared. It's much more fun to succeed with other people because you can blame them when things go wrong.
And some other random tidbits:
The answer to a lot of your questions is often in someone else's face.Limit your "always" and your "nevers"
Even though you are smart, you are still allowed to say, I don't know.
When you feel scared, hold someone's hand and look into their eyes, and when you feel brave, do the same thing
