Can you provide more info on burn-out? What it's like at its worst?
There's a difference between simply needing a vacation, and being completely and absolutely disgusted with your field and everyone in it.
I think that i am fortunate in that I direct all my wrath and loathing outward.
I haven't felt anything close to the same burnout since. Although I'm often stressed out over one thing or another, for the most part I'm pretty happy with the way everything is now.
