This step sounds counterintuitive, but it works. Play out in your mind all the things that could go wrong. Then picture yourself dealing with them, being very specific. "Imagining a worst-case scenario can help us tap into resources and creativity we didn't know we had," says Jonathan Alpert, LPC, a psychotherapist in New York City. "People often underestimate their ability to deal with a crisis." Mentally going over how you'd cope is a kind of rehearsal that builds inner strength.
