OK, hear me out, for forever I've considered myself bad at colour and colour theory. But in the past few years and in particular the last 12 months, I dabbled in painting miniatures. I did colouring on a cheap book with cheap markers.
One of the great joys of my adult life has been realizing that I can just pick up a new skill every so often, take a fun little class in it weekly for a year or two, and simply enjoy meeting people and getting medium proficient and not attempting to become professional in it at all!
