Being on phone, ipads and computer almost all the rest of my waking hours makes doing single tasks towards a larger project slowly quite meditative.

That would be pretty slow working. It's more entertaining than television and not bad exercise. And if you start with that attitude there is no helping you.

No, not really. Good dovetail joinery, without machines that do it perfectly, take a LONG time.

I've done quite a bit. (never tried a dovetailing machine tbh). It doesn't have to take a huge amount of time and a lot depends on exactly what you choose to do. Also you're moving the goalposts a bit there.

What else should I spend my hobby hours on? Woodworking is better than DotA2 or whatever kids play these days.
