Interesting framework. My 2c is that some hobbies are harder to do (top left corner) than others. Many listed in the article, eg, hiking, photography, climbing, etc: you can’t just do it always. I find I enjoy making music at home since I can just sit down for any amount of minutes and engage.
Making music is one where the gear is a huge part of it. I have some electronic music making gear (midi keyboard, drum computer and a synth), but I like tinkering with the gear and fiddling more than actually making music, lol.
It doesn't have to be. You can make music very simply. You can record on your phone. It doesn't have to be all the tracks and gear.
I have a friend who has searched his whole life for tone. Top end guitars, amps, more pedals than anyone I have ever seen. His actual guitar playing? Less complete, however, he loves it. Do what does it for you, in the way you like it. That is the best part of hobbies to me.
Yeah I enjoy that part also :) But it certainly feels like you also just need some of the gear (eg keyboard), whereas maybe with photography you could use the phone to start?
I went down a YouTube rabbit hole recently, watching people make music on the fly with GarageBand on their phone. There are some fantastically talented people out there.
