I don't generally make resolutions, although I do "set intentions" and maybe it's all pretty much the same thing.
Mostly, my ambition for 2021 is to stay more focused on the projects/activities that add the most value to my life. I have an unfortunate tendency to make sure that everything relating to "Plan B" and even "Plan C" is spic and span before I even start working on Plan A... and it really should be the other way around, because I sometimes find myself in the realization that I am only "part timing" Plan A because I am doing so much peripheral background work.
