[tadzik_]

Not OP but I have a similar workstyle: I work half-time for one client (remotely), 4 hours a week for another (also remotely) and occasionally take side gigs like teaching or something. The remote work is mostly in Norway, I live in Poland, so the pay cut is not noticable – the fact that "I could be making twice as much if I worked “normally”" is something that always is in the back of my head, but is somewhat dimished by the fact that I still make more than a typical fulltime salary would net me here in Poland.

Being a contractor in a niche technology (in my case it's Perl) is great for this, because the companies involved can't really say "work more or we'll find someone else" – we both know that they won't ;) Also, beyond 4-5 hours a day my (and afaik everyone else's) productivity is diminishing anyway, so it's not like they're losing much because of it.
