At the wrong gig, with the wrong bosses. I have the misfortune of being at one of those bad places now. I was at a much better place before, where if I went out of my way and saved a couple million, I'd actually be congratulated; boss would even let have the credit.

Never stay at a job where the culture is toxic. Even if the money is better. Nothing eats at the soul like being held down by feckless, petty careerists and control freaks.
