During much of my life I was pretty much behind the 8-ball financially. My wife was going to school, and we had children too. Our joint credit card debt was ~$40,000, mostly but not entirely for her tuition and expenses. Then I hit a few good investments, and without any real study or even reading I retired. I don't think there was much of the retirement literature around then that smacks us in the face every time we turn around today. My wife took off, and I was stuck with the cc debt, since she was a student with very little income. She got half of the positive assets in the divorce. I used a method I think called snowball to prioritize the debt paydown. It took me a while but I finished it. Our house was free and clear, and she didn't force me to sell since I was keeping the one child that was still at home. We finally sold it and split the proceeds a few years ago.
Anyway, I was kind of shell shocked so my goal with expenses, SS, and investments was to try to keep the monthly nut as close as possible to falling off a log difficulty. Since I waited to 70, my ss almost pays my expenses, though if I suddenly developed an urge to spend a lot of time in Monaco I think that would end. It helped me that I was renting when the property crash came, so I could pick up a good condo right where I wanted to live, though in a somewhat downscale part of the neighborhood relative to where I had been renting. Since then most but not all of the differential has closed. And a lot is going on here which I needed after I became single. I paid cash for the condo, which saved me money going in by creating a stronger negotiating position for me. Having no loan allows me to pick investments with little regard to income, so I save a bit in income taxes too. Anyway, I like it that I really have no financial anxiety. I don't have to cut corners, but neither can I go out of my way to try to spend more money.
I have learned quite a bit about frugality here. I knew these things as a boy. I always had little jobs and I saved the money, but beginning in adolescence I preferred the make it and spend it on pleasure plan.
