Please read the wonderful commencement speech penned and spoken by David Foster Wallace, an amazingly talented writer who committed suicide.
Note the big ideas he discusses. Note the idea of "worship" and moving beyond self-centeredness.
This is a very Yoga-ish (and Zen-like) "be in the moment!" speech. It is well worth your time to read it, to remember DFW, and to think about what we have or have not achieved since graduation, despite the hope we might have felt on that day.
What have you forgotten now that you thought you knew then? What have you learned?
If you haven't kept on learning, then college was--I fear--a waste of time for you.
College is not just four years. Education should never have a stopping point.
