If you have made a failure in speech, your song, your book, your article, if you have been placed in an embarrassing position, if you have fallen and hurt yourself by a false step, if you have been slandered and abused, do not dwell upon it. There is not a single redeeming feature in these memories, and the presence of their ghosts will rob you of many a happy hour. There is nothing in it. Drop them. Forget them. Wipe them out of your mind forever. If you have been indiscreet, imprudent, if you have been talked about, if your reputation has been injured so that you fear you can never outgrow it or redeem it, do not drag the hideous shadows, the rattling skeletons about with you Rub them off from the shite of memory. Wipe them out. Forget them. Start with a clean slate and spend all your energies in keeping it clean for the future."
