When health is absent, wisdom cannot reveal itself, art cannot manifest, strength cannot fight, wealth becomes useless, and intelligence cannot be applied.
Herophilus

All parents believe their children can do the impossible. They thought it the minute we were born, and no matter how hard we’ve tried to prove them wrong, they all think it about us now. And the really annoying thing is, they’re probably right.

The recipe for perpetual ignorance is: Be satisfied with your opinions and content with your knowledge.
Elbert Hubbard
Formulate and stamp indelibly on your mind a mental picture of yourself as succeeding. Hold this picture tenaciously and never permit it to fade. Your mind will seek to develop this picture!
Dr. Norman Vincent Peale
I don’t wait for moods. You accomplish nothing if you do that. Your mind must know it has got to get down to work.
Pearl Buck

Far better is it to dare mighty things, to win glorious triumphs, even though checkered by failure than to rank with those poor spirits who neither enjoy much nor suffer much, because they live in a gray twilight that knows not victory nor defeat.

Theodore Roosevelt
