The true object of all human life is play. Earth is a task garden; heaven is a playground.
There is no pleasure in having nothing to do; the fun is in having lots to do and not doing it.
Without play, there can be no experimentation. Without experimentation, there can be no learning. Without learning, there can be no progress.
You can discover more about a person in an hour of play than in a year of conversation.
The purpose of life is to live it, to taste experience to the utmost, to reach out eagerly and without fear for newer and richer experience.
Rest when you're weary. Refresh and renew yourself, your body, your mind, your spirit. Then get back to work.
