Why Financial Independence Retire Early (FIRE) May Not Be Suitable For Everyone?

Is there anyone in this community that has achieved FI? What did u do after that? Did you quit your job? Did you regret it and went back to work? How do you pass time meaningfully without a full-time job?

• I think those who let their job define who they are will face these problem. Work is everything to them.
• FIRE is a conscious effort, which require some sacrifice, else how can a normal office worker FIRE? He must do something extra, different from the peers.
• is very difficult to enjoy life and still be on track of FIRE. Unless having a high pay job.
• It is also dependent on personality, some people is ok to do nothing all day long and to be left alone.
• Get the FI 1st, then one can have an option to RE. FI is not so easy actually.
