Why stop there? :)
Find/Hire local goons to stalk you / monitor your chess games and whenever you blunder a piece, have them trash your car or go after members of your family.
(Erik => this is a business opportunity for chess.com!)
I seriously doubt you (or anyone for that matter) will be blundering ever again!
Jokes apart, you're really touching upon things NO book or video lecture really tells you about getting better at chess. I guess authors already assume you are MOTIVATED enough ... and chess coaches are chess coaches, not life coaches.
1. If you really want to get better, you will do whatever it takes to do so. You won't make excuses, you won't look for silver bullets or take the easy way out ... you'll work smart and work hard until you hit your goals.
2. The players who quickly improve are EXTREMELY OCD about making the same mistakes over and over again. They get burned a lot easier than the rest of us asbestos skinned folk here.
3. This "drive" to succeed diminishes once your own personal "sense" of complacency kicks in. Mine kicked in when I crossed 1700 USCF and until I get off my a## and "want" to push the envelope again, there's no magic potion or hours of studying that's going to get that number higher.
Hungry trumps "Nice to have", plain and simple.
When I was a 1200, I "wanted" to be a B-class player or move (1600+) more than anything else.
Now as much as I make excuses (oh, work/family demands are tough, blah-blah-blah) to cover it up ... the simple truth really is that crossing the 1800/Class A barrier is more of a a "Nice to have" and not a "I will do whatever it takes, take no prisoners" goal.
With that being said, know any goons for hire?
would it be possible to be hypnotized to play better chess.
assuming that you were hypnotized to know all variation of some opening.
opening lines could be memorized, and triggered if white plays d4.
I think it is possible.
before you reject this as ridiculous remember that :
sports athletes use self hypnosis to increase performance under pressure and to calm them down and give them self confidence.
imagine a tape you listen to while sleeping e4- d5 Sf3....
