As a husband, father of a 3YO girl and baby #2 on the way, this has been an enjoyable read with lots of great advice. Anyway here is what I came up with:
1 - Shoot par or at least beat my personal best (+3 73 shot back in 2015)
2 - Play my 100th course. I mentioned in the "Where have you played?" that I am currently at 81 and there are a ton of great tracks close to me that I have yet to play.
3 - Improve Par Saves from 30% to 45% for the year. I track a ton of stats and this is a glaring weakness in my game.
1 - Cut the cord. Cable is an insane waste of money.
2 - Read one book per month (golf or non-golf). I probably only read 1-2 books per year.
3 - Beat my personal best for miles run in a year.
4 - Run a half-marathon or 10k+ trail race.
