The rub of it is that we don’t know the future, the extra SS income stream if you delayed could be key if you run into health problems later in retirement that necessitate long term care. That stuff is expensive, and the places you’ll end up if you’re out of funds aren’t the places you want to be. Which isn’t to say your choice is bad, just offering another perspective where you might care about this even without kids or a spouse to worry about.
I realized it’s been just over seven years since I started pursuing FIRE proper. Prior to that I was saving and thought about retiring early but without much of a framework or depth. Since then our net worth has gone up five fold. Our lifestyle has also inflated a bit, we’ve bought a house and had kids. I’m contemplating pulling the trigger in the next year or two, or at least stepping back and changing what I’m optimizing for with work (eg. less hours and stress, more enjoyment and balance).
Looking back at some old mint emails I had about an early retirement goal I’d setup it’s fun to see how far I am ahead of that timeline and also how much lower the target was.
