Unpopular opinion: A solid, consistent full swing is more important than short game
Everybody says the same thing, work on your short game if you want to improve. The problem is if you don't have a consistent full swing you are chasing everything OB, setting yourself up in bad positions, and chunking and thinning balls all round. This is a miserable experience. Even if my full swing is still not good enough to avoid duffs and multiple OB's, it still is not enjoyable. I don't care what my score is, if I can't get consistent and solid contact I will not have fun and ultimately will not continue to play. So this is my suggestion instead, get the full swing very consistent. If you can do a consistent full swing, then your pitch and chip shots will be much easier as a lot from the full swing transfers over. I would rather have good contact with low dispersion and a high score than a lower score and multiple duffs and huge dispersion, but a great short game. So, that means I have more fun which means I continue to play and practice which means my short game gets better. The alternative is not to play as much because an errant shot with a full swing is way more frustrating than an errant shot with a pitch, chip, or putt. I'm not saying to completely forget about the short game, I'm saying to focus mostly on getting your full swing consistent and then to heavily focus on short game.
