As much as it is worthless to give advice in internet to strangers, I would advice all FIRE people to give a try of RE for a decent amount of time (say at least a year) already before FI. It is way easier to come up with money to live off for a year as opposed to the rest of your life. And frankly, I am quite sure most people do not like RE. Unless you count as RE a life where you do some kind of work that may pay less but what you really enjoy. In that case, why wait for FI and waste many years doing something you do not like? (Of course there are exceptions) And if you can't handle the risk of dropping out of your current job for a year, you may also want to seriously think if you can handle the risk of RE regardless of what your spreadsheet says, and again consider wheher you are wasting your life waiting for something you actually do not want.
