High handicap / beginner help

What are some of the best tips / tricks / drills etc you got to start improving?

I’m a beginner / high handicapper, been playing once a month for about 4 years so can swing a club but never consistent, not a brand new player but relative beginner. Joined a club this year and hoping to improve.

Unofficially play off 28-30 in society golf but hoping to get to 20-25 this year after a full year playing a couple of times a week!
