You have to color outside the lines once in a while if you want to make your life a masterpiece.

Where you see difficulty, I see opportunity.

The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge.

The finest emotion of which we are capable is the mystic emotion.

In their struggle for the ethical good, teachers of religion must have the stature to give up the doctrine of a personal god, that is, give up that source of fear and hope which in the past placed such vast power in the hands of priests. In their labors they will have to avail themselves of those forces which are capable of cultivating the Good, the True, and the Beautiful in humanity itself. This is, to be sure, a more difficult but an incomparably more worthy task.

Human knowledge and skills alone cannot lead humanity to a happy and dignified life. Humanity has every reason to place the proclaimers of high moral standards and values above the discoverers of objective truth.

In my experience, the best creative work is never done when one is unhappy.
