From The Secret - The Pruning Shears of Revision.

The great teacher Neville Goddard offered the following process in 1954 in a lecture entitled "The Pruning Shears of Revision." Every day, before you go to sleep, think through the events of the day. If any events or moments did not go the way you wanted, replay them in your mind in a way that thrills you. As you recreate those events in your mind exactly as you want, you are cleaning up your frequency from the day and you are emitting a new signal and frequency for tomorrow. You have intentionally created new pictures for your future. It is never too late to change the pictures.
