alt Hacker NewsWhen I had kids, I made a deliberate choice to focus on hobbies that were more amenable to interruption.
I mostly put aside music and any physical artform that required getting out and putting stuff away each session. Instead, I did a lot more writing, programming, and making stuff on my laptop since pausing and resuming was only a Ctrl-S away.
It also required learning the meta-skill of being able to break a large project into tiny pieces. I got a lot better at leaving notes to myself, not having too many projects going on in parallel, and thinking about problems when I was otherwise idle.
This makes sense but I don't think it works for me. I get irritable when I'm trying to do something like the activities you listed, if I can't focus on what I'm doing without interruption, and then that's bad for everyone, both the interruptee and the interruptor. This seems to be a personality thing (disorder?), my wife seems to be able to switch back and forth from working to parenting without it affecting her ability to perform on either task.
