People will always be jealous of something, anything you have or have done that they can't. When DW stayed home with the kids we got a chorus of "wish we could do that", when we mentioned our Hawaii plans, even her own mother was on about, "Wish I could afford a real vacation". I've noticed all the know it all elder (well, 40's anyway) males in the extended family ("Plastics!") all of a sudden stopped trying to give me financial advice as the answers to lots of questions weren't what they expected. "What's the payment like on that?" "None, we own the car."
We don't show off, my clothes are by Costco (Kirkland rocks!), but we also can see the speculative stares as relatives try to figure us out, and how we are already more FI then they.
I don't anticipate any issues with my FIRE, since I'll be retiring no earlier than early 50's. I bet it's weird for those of you who pulled it off in your 40's or earlier, but then again, who cares what they think?
Don't any of you simply say, "Investor" or something to that affect when asked about your career? "Self employed" would also work. I mean, heck, managing a multi-million dollar portfolio for safe withdrawals takes some work.
