I like the title of this thread, and I think I am living well in a challenging job right now.
Good salary and I can basically work from wherever I like. While I like the concept of retiring and doing nothing, I'm not quite ready to turn off the cash fire hose just yet. I would also miss the benefits, as well as the ability to work from sunny climes whenever I choose. I worry that I'll shrivel up in despair once I'm no longer needed to problem-solve and put out fires.
Maybe I'd leave if I had a hobby that I was passionate about. For now, I focus on the advantages and I just try to do the best I can when the work gets tough, which it does. People know that I'm a hard worker and I seem to have the respect of key people, and that goes a long way. All I can do is all I can do, and people seem to realize and appreciate that no one else could do much better.
Knowing that I can quit any time and that I have enough FU money to retire makes working seem "optional" as opposed to "mandatory", and that (IMO) helps a lot.
