I think it worth pondering "How much is enough?". Most of us have worked a large portion of our lives to earn wealth, if we count school, it's most of our lives. Hopefully, work wasn't all bad of course. My last boss I'm told is still working. He was promoted very early in his career, and then stalled out. It clearly meant a ton to him to make he next level (and then the next). I know about how much he earned, and it's quite a bit. He's probably not working so much for more wealth as more status, though once you retire such things are pretty trivial. I get asked on rare occasions where I worked, but never what my level was (not that it would make any sense to anyone anyway).
A buddy of mine just retired, he had told me his target was $3 million in assets, and his house was probably a quarter of that. He's pretty young, probably 55, but he should be able to continue with his lifestyle just fine.
I retired 11 years ago and have more in my IRA than I did then by a significant amoung (thanks Joe). So, I'm not spending my wealth, though I try at times.
But, if one is reasonably content with less expensive things in life, a lot less will do just fine. I could live myself on my SS alone if the condo was paid off. It's a matter of perspective, if you keep wanting more more more, you won't be fulfilled.
