*raises hand*
I love my work, don't care all that much about money, and have no plans to retire.
I still consider myself rather Mustachian because I live my best life through frugality, and because of that, I can easily afford to work very part time, which allows me to love my work.
I hated it full time because part of what makes my work so rewarding is that it's so goddamn intense. At 2 days a week though, it's fantastic. I can give my 110% every minute that I'm there, which allows me to perform at a really elite level.
I may or may not stay in my current job long term (whatever long term means), but I'll always stay active in my profession in some way, whether paid or not. My remaining days, at the moment, are spent on unpaid non-profit work, so that's already part of the balance.
I have 2 more working days left before I take a 6 week mini sabbatical, because I can.
