First, in fact, keep learning. Always be alive to the possibilities of the next experience, of thinking, doing and being.
When Buddha was asked, near the end of his life, to describe his secret, he answered bluntly: "I'm awake".
So be awake.Understand conventional wisdom, but be prepared to change it.
Feel as well as analyse; use your instinct alongside your reason. Calculate too much and you will miscalculate.
Be prepared to fail as well as to succeed, and realise it is failure not success that defines character.
I spent years trying to be a politician failing at every attempt and nearly gave up.

Sir Paul McCartney reminded me that the first record company the Beatles approached rejected them as a band no-one would want to listen to.
Be good to people on your way up because you never know if you will meet them again on your way down.
Judge someone by how they treat those below them not those above them.
Be a firm friend not a fair-weather friend.
It is your friendships, including those friends you made here at Yale, at this time, that sustain and enrich the human spirit.
