We all have 100% to deal with in our lives: 10% is important, 90% unimportant. The secret to a happy, productive life is to deal with the 10% and let the 90% slip.
Enjoy the successes that you have, and don't be too hard on yourself when you don't do well. Too many times we beat up on ourselves. Just relax and enjoy it.
Don't get hung up on a snag in the stream, my dear. Snags are not so dangerous-it's the debris that clings to them that makes the trouble. Pull yourself loose and go on.
