“ The purpose of life for man is growth, just as the purpose of life for trees and plants is growth. Trees and plants grow automatically and along fixed lines; man can grow as he will. Trees and plants can only develop certain possibilities and characteristics; man can develop any power which is or has been shown by any person anywhere. Nothing that is possible in spirit is impossible in flesh and blood. Nothing that man can think is impossible. Nothing that man can imagine is impossible of realization.
