Maybe it's bore out instead. It kind of feels like you need a hobby to fill "a void" that gives you purpose.
> So what comes next? Maybe try to make a small startup? Maybe switch to carpentry or farming? Tough it out for another decade until I can retire? What do people do after they get bored of tech?
- Startup: Lot of work, minimal pay in the beginning. Might be perfect to get back into the groove, but doesn't sound like you actually want that.
- Carpentry/Farming: Why not. Definitely gives living more meaning in my eyes. Hard work and you will likely ruin your body earlier than you want.
How about reducing working hours if that is an option and then take on volunteering work that has a meaning to you or teach/mentor kids.
> Side note: how and why did we as a society ruin that job?
