For me, I have 5, spanning 5 difficulty categories: super-easy, easy, intermediate, difficult, impossible. Getting 1/5 is a given, 2/5 is easily doable. Getting 3/5 would be good, 4/5 a great year and I added the impossible level because it sounds fun. This'd be like learning all the Taisha variations, or beating Shin Jinseo in a jubango. You know, something like that
Super-easy: Enjoy playing/studying Go. That also means shoving Go aside at the right moments, too.
Easy: Go through at least 100 Pro Games.
Intermediate: Do L&D every single day for at least 15 minutes!
Difficult: Detach from online rank. Stop letting that little number next to your avatar & username determine your actions. Tough one, but maybe the most important one.
Impossible: Reach stable shodan playing strength.
Tell me your resolutions. Don't use the same format if you don't want to, obviously
