Modeled on Charles Wheelan's 2011 Class Day Speech at Dartmouth College, this collection of refreshingly honest advice and observations is the antidote to those cotton-candy platitudes that are all too familiar to anyone who's ever worn a mortarboard. Armed with a PhD in public policy, many years of experience in social science research, and-perhaps most important-good-natured humor, Wheelan offers up 10½ head-turning aphorisms on happiness and success that anyone staring down the barrel of graduation needs to hear but probably hasn't heard yet. Celebrated New Yorker cartoonist Peter Steiner adds a touch of whimsy with his irreverent illustrations sprinkled throughout.
