One can have no smaller or greater mastery than mastery of oneself.

Time stays long enough for anyone who will use it.

Wisdom is the daughter of experience.

Imagine the end desired and feel its reality. Follow it through, and you will get definite results.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Where there is shouting, there is no true knowledge.

I've had quite a lot of luck with dreams. I've often awoken in the night with a phrase or even a whole song in my head.

Give me two hours a day of activity, and I'll take the other twenty-two in dreams.

The noblest pleasure is the joy of understanding.
