So, at the age of 47, after 25 years of obsessively pursuing my dream, that dream changed. For decades, in show business, the ultimate goal of every comedian was to host The Tonight Show. It was the Holy Grail, and like many people I thought that achieving that goal would define me as successful. But that is not true. No specific job or career goal defines me, and it should not define you. In 2000—in 2000—I told graduates to not be afraid to fail, and I still believe that. But today I tell you that whether you fear it or not, disappointment will come. The beauty is that through disappointment you can gain clarity, and with clarity comes conviction and true originality.
Many of you here today are getting your diploma at this Ivy League school because you have committed yourself to a dream and worked hard to achieve it. And there is no greater cliché in a commencement address than "follow your dream." Well I am here to tell you that whatever you think your dream is now, it will probably change. And that's okay...
I have told you many things today, most of it foolish but some of it true. I'd like to end my address by breaking a taboo and quoting myself from 17 months ago. At the end of my final program with NBC, just before signing off, I said "Work hard, be kind, and amazing things will happen." Today, receiving this honor and speaking to the Dartmouth Class of 2011 from behind a tree-trunk, I have never believed that more.
I can't think of better advice to give to recent college graduates--and anyone, really.
You can read the text of the speech here (but it's much more fun to watch it).
