Consult Not Your Fears
I saw this in someone else's cubicle. I found it so relevant, that I had to take a Post-It (tm) note and jot it down.
"Consult not your fears but your hopes and your dreams.
Think not about your frustrations, but about your unfulfilled potential.
Concern yourself not with what you tried and failed in, but with what it is still possible for you to do.“
Pope John XXIII
