If You Can..

If you can start the day without caffeine;
If you can get going without pep pills;
If you can always be cheerful, ignoring aches and pains;
If you can resist complaining and boring people with your troubles;
If you can eat the same food every day and be grateful for it;
If you can understand when your loved ones are too busy to give you any time;
If you can forgive a friend's lack of consideration;
If you can overlook it when those you love take it out on you when,
  through no fault of your own, something goes wrong;
If you can take criticism and blame without resentment;
If you can ignore a friend's limited education and never correct him;
If you can resist treating a rich friend better than a poor friend;
If you can face the world without lies and deceit;
If you can conquer tension without medical help;
If you can relax without liquor;
If you can sleep without the aid of drugs;
If you can honestly say that deep in your heart you have no prejudice
  against creed or color, religion or politics; then, my friend, you are
  almost as good as your dog.

The Laughing Heart by Charles Bukowski

your life is your life
don't let it be clubbed into dank submission.
be on the watch.
there are ways out.
there is a light somewhere.
it may not be much light but
it beats darkness.
be on the watch.
the gods offer you chances.
know them.
take them.
you can't beat death but
you can beat death in life, sometimes.
and the more often you learn to do it,
the more light there will be.
your life is your life.
know life is your life.
know it while you have it.
you are marvelous
the gods wait to delight
in you.
