Don't follow any advice, no matter how good, until you feel as deeply in your spirit as you think in your mind that the counsel is wise.

Destiny

Nature is at work.. Character and destiny are her handiwork. She gives us love and hate, jealousy and reverence. All that is ours is the power to choose which impulse we shall follow.

Self-interest

A wise unselfishness is not a surrender of yourself to the wishes of anyone, but only to the best discoverable course of action.

Visualization

Try out your ideas by visualizing them in action.
