I found this inspirational 2011 graduation speech by Conan O'Brien at Dartmouth College. It is a great mix of silly, witty, inspirational, and profound. Check it out. For those in Medicine and medical training, your dreams may change over time... and that's ok.
"Your perceived failure can become a catalyst for profound reinvention."
-- Conan O'Brien
"No specific job or career goal defines me, and it should not define you."
