I have but one lamp by which my feet are guided, and that is the lamp of experience.

Genius is the ability to renew one's emotions in daily experience.

Only those who have learned the power of sincere and selfless contribution experience life's deepest joy: true fulfillment.

We should not look back unless it is to derive useful lessons from past errors, and for the purpose of profiting by dearly bought experience.

Take time to gather up the past so that you will be able to draw from your experience and invest them in the future.
