It is not length of life, but depth of life.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate.
To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.
Insist on yourself. Never imitate.
Don’t waste your life in doubts and fears: Spend yourself on the work before you, well assured that the right performance of this hour’s duties will be the best preparation for the hours or ages that follow it.
Every artist was first an amateur.
Unless you try to do something beyond what you have already mastered, you will never grow.
The only person you are destined to become is the person you decide to be.
Do not follow where the path may lead. Go, instead, where there is no path and leave a trail.
Most of the shadows of life are caused by standing in our own sunshine.
