If you're not failing every now and again, it's a sign you're not doing anything very innovative.

Every child should have mud pies, grasshoppers, water bugs, tadpoles, frogs, mud turtles, elderberries, wild strawberries, acorns, chestnuts, trees to climb, brooks to wade in, water lilies, woodchucks, bats, bees, butterflies, various animals to pet, hayfields, pine-cones, rocks to roll, sand, snakes, huckleberries and hornets; and any child who has been deprived of these has been deprived of the best part of education.

 我们应该为人们的诞生而哭泣，而不是为他们的死亡。

领导力不在于掌控，而在于照顾好你所负责的人。
