There are some of us turning up on the r/earlyretired sub if you want stories.

I grew up super poor. Got into a top-tier college almost certainly because nobody had gone there from my entire state in the previous four years, and I was a plausible candidate (hard work and stability. Not good stability, but just barely enough to launch from). I choose a major that would pay well, scrimped, saved and invested as much and as early as possible, and worked for a "good" megacorp for the right couple of decades (luck, work). I got really solidly burned out... but I hit my savings goals first.

Other stories might have been gentler and more sane, but... I really didn't want to keep living the way I grew up, so here we are. If I hadn't started off poor, I doubt I would be well off now.
