Sometimes we stare so long at a door that is closing that we see too late the one that is open.
Alexander Graham Bell
Don’t argue for other people’s weaknesses. Don’t argue for your own. When you make a mistake, admit it, correct it, and learn from it immediately.
Stephen Covey
Nothing great has ever been achieved except by those who dared believe that something inside them was superior to circumstances.
Bruce Barton
When health is absent, wisdom cannot reveal itself, art cannot manifest, strength cannot fight, wealth becomes useless, and intelligence cannot be applied.
Herophilus

Cathy Guisewite
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
