Take a "vacation" and be someone else while you're gone. Possibly use another name. Make up a new personal history for yourself. This is a version of the Astonish Yourself! experiment described elsewhere in the blog. Don't use this as a period of debauchery...act "normal" (relatively)...just act like like someone other that the habituated everyday you.
As they say...what happens in Vegas, stays in Vegas. Observe carefully how it feels to now be the old "you" when you get back home. Which "you" is the "real" you?
