Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever.

Sometimes pain can drive a man harder than pleasure.

Much of your pain is self-chosen.

Pain is love and love is pain.

Even pain has its joy.

Joy and pain are like sunshine and rain.

The pain of the mind is worse than the pain of the body.
