You essentially work a half day. Burying the lede here a bit.
So, no. I do NOT just work a half-day, I prioritize, I multi-task, and it's very difficult to maintain this lifestyle.
Serious question, why bother? Any normal job would have you working less (assuming it’s true that you never get a free weekend or holiday, which I kind of doubt). What do you get out of this? The ultimate satisfaction of helping a stranger receive email instead of being with your family on Christmas?
