Oh, my friend, it's not what they take away from you that
counts.  It's what you do with what you have left.
 - Hubert Humphrey

Undertake something that is difficult; it will do you good.
 - Ronald E. Osborn

Feel good first.  Most people think they'll feel good once
they reach some goal.  The problem with putting off feeling
good about yourself until you hit a certain goal is that it
may never happen.  By linking happiness to something you
don't have yet, you're denying your power to create it for
yourself.
 - Steve Chandler, "100 Ways to Motivate Yourself"

No one lives long enough to learn everything they need to
learn starting from scratch.  To be successful, we
absolutely, positively have to find people who have already
paid the price to learn the things that we need to learn to
achieve our goals.
 - Brian Tracy

When you become detached mentally from yourself and concentrate
on helping other people with their difficulties, you will be
able to cope with your own more effectively.  Somehow, the
act of self-giving is a personal power-releasing factor.
 - Norman Vincent Peale

Ability is what you are capable of doing
Motivation determines what you do
Attitude determines how well you do it
