After losing more than 200 points in a day, I discovered an incredible technique: in every puzzle, I ask myself "what is the move that I would never ever play in any game no matter what". And voila, it's almost always the correct answer!
Final note: I really suck at chess
George Costanza also tried this (with success) in the comedy sitcom Seinfeld (The Opposite episode). The problem is of course that there are usually more than 2 "opposite" possibilities in life and also that the person is seldom wrong with literally every decision they make.
As for solving chess puzzles, don't get discouraged. You aren't that bad, you just haven't gained enough chess knowledge and pattern recognition yet.
Whenever you attempt a puzzle and get it incorrect, it is useful to analyze that position (usually with Analysis board) and try to reason why the solution is "best" and try to reason how you could have found that originally. It just takes some practice and experience, but once you get the hang of it, then puzzle solving will become easier for you.
