Indoor rock climbing for fitness. I only do bouldering because no friends and still want to get stronger.
Woodworking.
Various DIY projects.
Motorcycle rebuilding and riding - I only ride sports bikes… they need rebuilding too.
Driving cars and all that goes into making that a hobby (repair, maintenance, detailing, etc.).
Photography - this mostly only gets done while traveling but I’m ready for almost anything. (Ultra wide underwater with strobes to 1200mm wildlife to studio portrait photography to aerial drone photography… I am ready)
YouTube. This is basically a hobby at this point and it’s purely consumption. I watch so much random shit that is focused on teaching and learning new things. I’m not watching people react to stuff or anything like that - instead I’m learning about techniques for building new homes, struggles with rebuilding cars (the more I watch the less I want to do it…), woodworking techniques, etc. Ultimately it all has an entertainment bend and isn’t super dry content but I am also learning way more than your average citizen. I would say youtube is likely responsible for why I’ve been able to hold a conversation on nearly any subject for a while now. I’ll meet someone and can engage with them on their subject of choice because I’ve been exposed to so much. Most people are like - “how do you know all this?? This is what I did my graduate degree on.” If you love to learn - lotta high quality content on YouTube that feeds that addiction.
