I'm seeing a therapist later this month because in a talk with my GP she saw strong enough hints of ADHD to send me there, and the kind of situations and some feelings talked about in the article came up a lot in the conversation.
I size up my oil paints against the old masters, not the old ladies in the atelier. I paint miniatures way better than average but hang around with Golden Demon winners so I always find myself wanting. Can play beautiful Renaissance pieces on my uke, but infuriatingly not at a professional performance level. Can win many sim races, but not against the top 0.1%, yet I size myself against their telemetry and laptimes. I dabble in Chess but being forever stuck around lowly 1300 ELO makes me feel dumb. My dead side projects cemetery has subdirectories approaching 3 figures. I go out and cycle with my brother but I huff and puff while he tops the Strava segments and wins the regional amateur championship again.
So too many days I just sit and do nothing, or just look for something else to enjoy for a few months until I become an unhappy promising beginner at yet another thing, adding to the overall problem.
