I wouldn't try to FIRE on only $330,000. Maybe it would work if you retire to a homeless shelter?
You're just as bad as the people who fling **** in the comments section of these types of articles. "I can't do it, and therefor nobody can!" You'd have to be homeless!"
Yea people who fling asterisks are full of shit!
Overall, I felt the general feel in the comments was more positive than many articles. It could be do that it referenced MMM directly which may drive more people there who are interested in MMM, thus a more positive feeling about the concept.
8% with a stash of 330k invested "close ended funds and high dividend stocks" would make me feel uncomfortable if I were to attempt FIRE. If it is comfortable for this individual, go for it.
