THE NEW YORK TIMES BESTSELLERI once began a list of the contradictory notions I hold:Look before you leap. - He who hesitates is lost. - Two heads are better than one. - If you want something done right, do it yourself. - Nothing ventured, nothing gained. - Better safe than sorry. - Out of sight, out of mind. - Absence makes the heart grow fonder. - You can't tell a book by its cover. - Clothes make the man. - Many hands make light work. - Too many cooks spoil the broth. - You can't teach an old dog new tricks. - It's never too late to learn. - Never sweat the small stuff. - God is in the details. - And so on. The list goes on forever. Once I got so caught up in this kind of thinking that I wore two buttons on my smock when I was teaching art. One said, "Trust me, I'm a teacher." The other replied, "Question Authority."[signature]Fulghum
