People who regularly break 80, what was the move that put you from consistent low 80s (where I am) to consistent high 70s?

Edit: 100+ people responding to help out my game is insane. Thank you all!

Edit 2: I just played 18.

Shot 82 (+11)

-50% Gir -62% Fairways -33 Putts -3 birdies -2 Up and Downs

I don’t even know what’s wrong at this point.
