Actually I think that once you have done the work of revealing and examining the changing is the easiest part, it almost just follows and happens by itself. (Because these subconscious things drive our thoughts and actions and once we make them conscious, their hold is released and our behavior is freed). And yes, the revealing I think is the most difficult part. Reveal at your own pace, however. You can build some trust first and start with the small things and save the bigger things for later.
