Yeah i'm the world's worst listener and I absolutely hate it so I'm always trying to find ways to fix it. I can watch entire season runs without knowing what happened. I've been known to go to the cinema and leave without having paid attention to a single thing. I've listened to literally hundreds of podcasts but don't bother any more because there's just no point. Five minutes at best and my mind goes elsewhere.
Ironically if there's something else I'm trying to focus on and there is a TV or something happening in my peripheral I often can't tune it out.. lol
I've been cutting my own hair for the last 14 years for this exact same reason. I still have the same pair of clippers too so I must have hundreds by now
