Your Success and Happiness Lie in You

If you give a part
  of yourself to life,
the part you receive back
  will be so much greater.
Never regret the past,
  but learn by it.
Never lose sight of your dreams;
a person who can dream
  will always have hope.
Believe in yourself;
  if you do, everyone else will.
You have the ability
  to accomplish anything,
but never do it at
  someone else's expense.
If you can go through life
  loving others,
you will have achieved
the greatest success of all.
