A must read Op-Ed by David Brooks called "It's Not About You" in the New York Times on the real meaning of graduating - and it is not about "you" in spite of what most graduation speeches say.
From the Op-Ed
"The graduates are also told to pursue happiness and joy. But, of course, when you read a biography of someone you admire, it’s rarely the things that made them happy that compel your admiration. It’s the things they did to court unhappiness — the things they did that were arduous and miserable, which sometimes cost them friends and aroused hatred. It’s excellence, not happiness, that we admire most.
Finally, graduates are told to be independent-minded and to express their inner spirit. But, of course, doing your job well often means suppressing yourself. As Atul Gawande mentioned during his countercultural address last week at Harvard Medical School, being a good doctor often means being part of a team, following the rules of an institution, going down a regimented checklist."
