Make a New Year's Theme instead - CGP grey had a video on this. Then, when the first things you try related to the theme fail (or feel bad, or don't make sense anymore), pick something else in the theme and try that instead.
Productivity themed year got me to:
Learn AutoHotkey
Setup a central collection of notes
Use a calendar app properly
Finish several (profession related) books
Track my internet time
and more! And, for maybe the first time, I finally feel like I did something with this whole resolution thing.
For me, actually put things in it, setup notifications for the day before (and on a device I actually see), add family, and check it before scheduling (some) things.
I kept mine by following this advice before I watched the video. The general idea was i wanted to have my week off in the holidays with my family and not be worried about the future, kinda evolved to a "how I view myself" theme would be the best way to describe it. Went hard at gym for 6 months before long term injury came up again, so focused on work and uni instead. Dropped one uni paper but got a- in the other, and turned my company around from 20% monthly loss to 10% profit.
