OP: have you birdied every hole on your home course? If so, have you eagled every hole there? These could be good ones if you are bored with your home course. Other suggestions: go ___ holes in a row without a bogey, go ___ rounds in a row without going over par.
For me:
Goal 1 is to break 100, which should be very doable since I shot a 103 last year in my first full season of playing
Goal 2 is to get a handicap (index) below 30
The two things I need to do to achieve them is to cut down on big misses on long shots and get some actual practice on my short game off the course. Way too many times where I've needed 2 chips to get on the green. It's always tough for me to hit the range more than once a week, but I have a few lessons purchased I'm going to use soon, and hopefully the weather in NYC will become more conducive to golf soon (range is covered/heated, fortunately).
