We don't usually refer to our plans as retirement, as I already haven't been getting paid for most of my work for a few years and we tend to avoid goals that sound like they limit options. We make no claims to circumnavigate in our sailboat, just to cruise as long as we are enjoying ourselves DH often refers to his pending decision to leave the workforce as an indefinite sabbatical.
I always liked the term "of independent means," as it also avoids the discussion of "what is wealthy" (not sure why this term is so problematic on wealth accumulation forums, like here and bogleheads, but it is. According to many, we are not wealthy, but we certainly meet our own definition. Drives FIL bonkers that we refer to ourselves as wealthy with a similar networth to his own).
And so, I think I have finally identified an acronym we can embrace: FOAM (Folks Of Autonomous Means)
What color is your FOAM?
