Earlier quoted context omitted.
How do you avoid burnout when you're being so self-sacrificial? Seems like it'd be a big risk.
Make sure you're getting compensated properly, and make sure it's work that's visible. If you can't do those two things...well, enjoy your burnout. :(
But there is something to add to this, I got burned out, took a mini-sabbatical and came back a rockstar with a pay raise.
I guess the invisible work became visible in my absence. :-)
An additional side-benefit, I became human again.
