A.A.Milne, who wrote the Winnie the Pooh books. Reading those stories now as an adult show me what terrific insight Milne had into the nature of human beings:
Rabbit, the person always on the go and never stopping to smell the flowers (like most Americans) and consequently, never really gets things done efficiently
Eeyore, the person who indulges in feeling sorry for themselves all the time, and strives to elevate themselves by putting others down
Owl, the person who is pompous and full of themselves, proud of their vast knowledge and left-brained thinking and yet, doeesn't really know anything
Tigger, the person with an impregnated sense of a "can do' attitude, always sure they can do anything and everything, refusing to recognize their own personal limits. A jack of all trades, they can do everything, but consequently, can't do anything really well.
Piglet, the small who is all too aware of just how small he is; the common man. Always worrying about things that haven't come to pass, and making decisions on "what could happen". As long as he keeps this attitude he stays a small person, unknowingly keeping himself down and preventing himself from reaching his potential.
Pooh, the simple minded person whom people assume isn't really smart, yet things always seem to work out for him without him even trying. The Tao of Pooh illustrates this concept beautifully, pointing out that because he doesn't strive to attain anything, he recieves everything.
