You are not mentally developed by what you read, but by what you think about what you read.
Wallace D. WattlesThere is no labor from which most people shrink as they do from that of sustained and consecutive thought; it is the hardest work in the world
Wallace D. WattlesTo fix your attention on the best is to surround yourself with the best, and to become the best.
Wallace D. WattlesA person's way of doing things is a direct result of the way he thinks about things.
Wallace D. WattlesCast out envy; you can have all that you want, and you need not envy any man what he has. Above all things, see to it that you do not hold malice or enmity toward any one; to do so cuts you off from the mind whose treasures you seek to make your own. Lay aside all narrow personal ambition and determine to seek the highest good.
