I have tried and failed at many things many times, but because of those failures, I feel that the victories have tasted so much better.  Here are some quotes on failure . . . and success:

• A man may fail many times, but he isn’t a failure until he begins to blame somebody else . . . J. Paul Getty
• Failure should be our teacher, not our undertaker.  Failure is delay—not defeat.  It is a temporary detour, not a dead-end street . . . John Maxwell
• Success is never final; failure is never fatal . . . Joe Paterno, football coach
• Fall seven times, stand up eight . . . Japanese Proverb

And my personal favorite of the bunch:

• There is nothing wrong with making mistakes.   Just don’t respond with an encore . . . New England proverb
