Life is a series of collisions with the future; it is not the sum of what we have been, but what we yearn to be.

Effort is only effort when it begins to hurt.

Love is that splendid triggering of human vitality... the supreme activity which nature affords anyone for going out of himself toward someone else.

Order is not pressure which is imposed on society from without, but an equilibrium which is set up from within.

Life is an operation which is done in a forward direction. One lives toward the future, because to live consists inexorably in doing, in each individual life making itself.

I am I plus my circumstances.

Tell me to what you pay attention and I will tell you who you are.

Excellence means when a man or woman asks of himself more than others do.

We distinguish the excellent man from the common man by saying that the former is the one who makes great demands upon himself, and the latter who makes no demands on himself.

We cannot put off living until we are ready.
