Making a mistake is falling down; failure is not getting up again.

That the sky is brighter than the earth means little unless the earth itself is appreciated and enjoyed. Its beauty loved gives the right to aspire to the radiance of the sunrise and sunset.

Surely there is no road of effort so steep but a loving deed may soften its hardshness.

Usually they are quick to discover that I cannot see or hear.... It is not training but love which impels them to break their silence about me with the thud of a tail rippling against my chair on gambols round the study, or news conveyed by expressive ear, nose, and paw. Often I yearn to give them speech, their motions are so eloquent with things they cannot say.

The marvelous richness of human experience would lose something of rewarding joy if there were no limitations to overcome. The hilltop hour would not be half so wonderful if there were no dark valleys to traverse.

Hope sees the invisible, feels the intangible, and achieves the impossible.

If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, so thoughtful that it becomes a philosophy of life. If, in short, I am an optimist, my testimony to the creed of optimism is worth hearing.
