Don't waste your time complaining about what just happened or you will waste the time you have to enjoy. It was bad enough when it happened the first time so reliving it over and over again in your mind wasting your energy and time again and again. Enough is enough don't put your self through it again and again. Acknowledge it then "Just Flush It" out of your mind so you can enjoy today instead wasting it. You only have so much time on this earth so don't waste it.
