The worst thing you can do is nothing. The one thing in the world, of value, is the active soul. However brilliant an action, it should not be esteemed great unless the result of a great motive. You must act as you breathe. It is the mark of a good action that it appears inevitable in retrospect.
All life is an experiment.
The more experiments you make the better. What if you do fail, and get fairly rolled in the dirt once or twice. Up again, you shall never be so afraid of a tumble. Some men are heavy and stupid from undigested learning.
