What industry are you now in, that you can work 20h/week? Just curious, you are living my dream.

I've been doing devops contracting for a startup at 25 hours/week lately. I'm digging it a lot, because it gives me two days during the work week to go outside and plenty of time to work on my own stuff. I don't feel guilty when I go home after one of those work days and don't put time in on one of my projects. That's a powerful thing.

(Shameless plug: one of my arrangements is ending soon and I'll be taking on more devops and automation work; at every place I've been I've added pretty big multipliers to engineering output in a fairly short amount of time, and my email's in my profile if that appeals to you.)

I work in a Teradata shop in a major financial institution and the hours are reasonable and the work is borderline relaxing. There is a nice middle ground between 20h/wk and the startup meatgrinder if you seek it.

For me 20h/wk is middle ground between fulltime and not having to work at all.

It literally is in the middle between fulltime and not having to work at all, so it's not just you.

I play poker professionally so I get to set my own hours.
