This all depends on your relationship with work.
I retired a few years ago due to medical issues, I had to leave work entirely. But I ended up taking on a lot of volunteer work because that's what I enjoy. So for me, "work" is a key part of my best life. I'm just very, very picky about the work I do.
My spouse and I had many talks for a long time about what the best use of my work energy would be, and we ultimately decided I would retrain to be able to be paid extremely well for my part time work that I would be doing anyway.
Now I'm back to paid work part time and it's great.
So it all depends on whether work is cock-blocking you from doing something else you would prefer doing.
If it is, then putting off access to that quality of life may not be a good trade. But if your best life includes taking on a lot of challenging projects that create value, then it may be absolutely ideal to stretch out the years where you get paid for doing so.
For me, it's so ridiculously obvious to keep paid work in my life. The more years I keep income flowing in, the more years compounding can work on my 'stache, and the fewer years I need to worry about SORR, etc.
But I'm not "putting off" my ideal retirement. I've been retired since 2020, this really is my best life. I'm just back to getting paid for what I was doing for free.
Hilariously for me, as long as I'm getting paid well to do something, it's actually easier for me to have stricter boundaries and not let the work take over. When it's volunteer work and there's literally no one else with my skills able to take over, it's very easy for the sense of obligation to take over and let the work seep in more than is optimal for me.
I basically need to have a paid job to keep myself out of trouble and keep me from working too much, lol
Examine closely what you see if missing from your life. What unmet needs are motivating you to FIRE, and can those needs best be met by hunkering down and putting off your happiness for a full retirement, or can they be best met by finding a way to generate income in a highly balanced life?
No one can answer this for you.
But I can tell you that for me, figuring out how to generate income doing the kind of work I love as part of a rich lifestyle feels like life on easy mode. It's also exactly what I took as inspiration from MMM's life choices.
I had little interest in his story pre-FIRE and was far more fascinated by the fact that he made the bulk of his money *after* retiring, by focusing on his ideal lifestyle.
I think a lot of folks write that part off, but to me, it really resonated. I don't really see him as being someone who saved a lot and then retired on a modest, frugal budget. I see him as someone who saved more than enough FU money to start building the life he really wanted.
What does that life look like for you? Do you even know? What exactly is currently acting as a barrier?
