Every dollar invested in responsible forestry today grows into a hundred dollars of environmental and economic value tomorrow.

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.

Nothing is funnier than unhappiness.

Ninety-nine percent of the troubles that threaten our civilization come from too optimistic, therefore we should have a system where the accounting is a way more conservative.

A good system design is one that makes it easy to do the right thing and hard to do the wrong thing.
