Basically, you can live your life in one of two ways. You can let your brain run you the way it has in the past. You can let it flash any picture or sound or feeling, and you can respond automatically on cue, like a Pavlovian dog responding to a bell. Or you can choose to consciously run your brain yourself. You can implant the cues you want. You can take bad experiences and sap them of their strength and power. You can represent them to yourself in a way that no longer overpowers you, a way that "cuts them down" to a size where you know you can effectively handle things.
