Hitting balls with regularity is the best thing you can do. I used to play about once a week, got to averaging low 90s to upper 80s. Never got to the low 80s really though.
This past year I've only been out about 5 times. Between not getting out and getting over some sciatica, the skills fall off quickly. I'm not a natural either so it's an up hill climb. Back to shooting in the hundreds. At this stage the knowledge from lessons can become a burden because I'm thinking about hip angles and wrist rotation and I need to back up and remind myself what simply hitting down feels like, lol.
I've just had to reset my mind and remember things that I tell friends who are just starting. A 6 iron off the tee has been saving me more strokes than anything I've learned in a lesson. But I'm glad it's still fun for me. I have some friends who would probably just stop playing if they back slid that much. Putting your ego to the side and remembering that you're smacking balls in a field is the best golf lesson you can ever get in my opinion.
*And deciding what type of golf you really want to play. Get the ball in the hole or try to drive the ball 300. Most people don't get to play both ways, so you just pick one and have fun, lol.
You can still have fun shooting in 100s if you can crack it 280+ in the air every time. Even if you miss every fairway, it's fun to watch guys who can hit those distances catch one straight.
