A child . . . must feel the flush of victory and the heart-sinking of disappointment before he takes with a will to the tasks distasteful to him and resolves to dance his way through a dull routine of textbooks.

As selfishness and complaint pervert and cloud the mind, so love with its joy clears and sharpens the vision.

Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing.

Although the world is full of suffering, it is full also of the overcoming of it.

Your success and happiness lies in you. Resolve to keep happy, and your joy and you shall form an invincible host against difficulties.
