Remember that a burst of enthusiasm usually accompanies a new idea and that the tendency is for you to hurry and tell someone. The mental energy generated by your idea is thereby dissipated in talk rather than in thought. After you talk about it for while, you grow tired. Your idea flows out through the mouth like a weak, shallow creek. The energy that would have developed the idea is released and the idea dies. Don't you talk to anybody about any idea until you have fully developed it!
