Don't think about your future, especially right now. You'll miss my speech. There will be plenty of time to contemplate your future right after the ceremony, but then you'll miss all the celebrating and adulation. So just wait until you get home and have a good think about something that will happen in the future that will make you happy.
When I graduated from college, I spent a lot of time thinking about how cool it would be to be on the Johnny Carson show. A few years later, it happened. We appeared on the "Tonight" show, Joey Bishop was the guest host. We were dreadful. For years I ran into people who would stop me and say, "Hey, I saw you on the "Tonight" show. Huh... What's Joey Bishop like?" Eventually I got over the embarrassment, but I never got those years back — years I spent waiting for some future event to make me happy. I had tricked myself into thinking, "As soon as I get there, I'll be OK."
I work in a business where almost everyone is waiting for the next big thing. Sometimes it comes, and sometimes it doesn't. But it doesn't matter that your dream came true if you spent your whole life sleeping. So get out there and go for it, but don't be caught waiting. It's great to plan for your future. Just don't live there, because really nothing ever happens in the future.
