What’d you guys do to get better

Been golfing seriously around 2 years I’m talking range 3-5 days a week and 1-2 rounds a week, I’ve gone from a 27 handicap to a 10.8 Averaging in the low 80s, occasionally breaking 80s on easier courses.

What did you scratch golfers do to get better? I feel like I’ve been stuck at 10 handicap a while, All the practice I do, my game still has a lot of leaks, Any tips?
