Being gentle means forgiving yourself when you mess up. We should learn from our mistakes, but we shouldn't beat the tar out of ourselves over them. The past is just that, past. Learn what went wrong and why. Make amends if you need to. Then drop it and move on.
Sean CoveyAll the events of your past have formed a lens, or paradigm, through which you see the world. And since no one's past is exactly like anyone else's, no two people see alike.
