Use your health, even to the point of wearing it out. That is what it is for. Spend all you have before you die; do not outlive yourself.

We are all born for love. It is the principle of existence, and its only end.

We are not here merely to make a living. We are here to enrich the world.

We are not human beings having a spiritual experience. We are spiritual beings having a human experience.

Nothing in life is to be feared. It is only to be understood.

When you're chewing on life's gristle
Don't grumble, give a whistle
And this'll help things turn out for the best...
And...always look on the bright side of life...
Always look on the light side of life.
