This hobby shoehorns many disparate pursuits into one box: musical appreciation, music library building, system building, community building & participation, wife/girlfriend management, technical know-how, gear lust, budgeting (or lack of), and the addictive dopamine hits from new acquisitions. It can definitely be hard to find a good balance here!
