“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-in action. Nothing that man can imagine is impossible of realization.
Man is formed for growth, and he is under the necessity of growing.
It is essential to his happiness that he should continuously advance.”
