All those stupid things you’ve done. All the hateful words said and spiteful acts performed. All those poisonous thoughts. All those times you went to sleep with your bitterness gnawing away inside you like rats in the cellar... all those times you woke in a cold sweat with a lurch and a dread. Let them go. Move on. Don’t let all the mistakes you’ve made cripple your chances of doing things better in the future.
But don’t forget. Don’t forget how terrible, how utterly despicable you can be.
