I'm not quite sure what you mean by income. I assumed that it was income from my investments, and others may too. On re-reading, I suspect that you are talking about post-fire work income (side-gigs or such).
Yes, I'm sorry for being less than clear. Obviously the mindset of an FI, "living of off investments" person is different than that of a current wage slave like myself.
You have the "gist" correct. I'm trying to ascertain the likelihood of "extra" or "unplanned" income coming into play for someone with a MMM mindset who has already FIRE'd. Since everyone FIREs with different plans, I found it difficult to word the questions correctly.
What I didn't (or don't) want was(is) someone who FIRE'd on the 4% rule, but has achieved 10% real returns, voting they have earned more than anticipated. An intrinsic part of a 4% rule FIRE is a high likelihood of overachieving returns (same with increasing rents on real estate cash flow, ect). Now, that same person who also started a small consulting business for fun (which wasn't part of the original plan) and has brought in unplanned "income" of a few grand per year, would vote "yes" for unplanned income.
Thanks to everyone who has voted, please keep them com'en!
