Good for them, they are a real inspiration to all of us who aspire to reach FIRE. I am really happy for them but must admit these articles make me a bit sad when I realize how clownish I was most of my working life, earning 6-figure salaries from my late 20s through late 40s, but spending as if there were no tomorrow. It took me a real hit -losing my job at 49 at the top of my career, to realize how stupid I had been all these years. I'll never know what FIRE in my 30s or 40s would feel like, but thanks to finding MMM a few years ago, I might be able to FIRE this year at 58, not as early as I would have liked or could have done with a bit more brains, but still earlier than most. While my numbers are tight due to a number of investment mistakes, FIRE very feasible thanks to our frugal lifestyle and low financial needs.
