The idea is that depression produces lots of symptoms (as described in those notes), but it is all produced by a single habitual unconscious process. The process is withdrawing participation from your own internal decision making process. It is hard to talk or reason your way out of this because the transition to the depressive state is unconscious. However, snapping your fingers when you decide tiny things that you make up TRAINS your subconscious into participating and enjoying the little decisions. I know that this sounds like a superficial trick, but it really isn't. It's worked for a lot of people and sometimes it works dramatically and rapidly too... see for instance
