FIRE: Why are many people frowning upon the idea of early retirement?

Becoz they dont know how to enjoy life? So many things to do only problem is no time , no money.

I think they are just extroverts who depended on their workplace to fulfil their need for social interactions. As an introvert, I think it will be comfortable spending time doing your own hobby, learning a skill, reading an entire library, etc, with probably weekends spent to catch up with your closer group of friends who might not have retired yet.

Ultimately, I believe achieving FIRE give you the option to retire, and you can don't stop working. It will give you a peace of mind, to know you can just resign immediately if your boss give you hell without worrying about your livelihood.

That said, keep working on it, and all the best.

I can totally relate to this! I'm 31 this year, married with a daughter of 1.5 year old. When I told people my aim is to retire at 40, they commented things like "oh you'll be bored and lonely". No I won't, because my plan is to retire with my wife. Because my life is more than 9-6.

when I finally retire at 40 (hopefully), I'll have time to watch movies in the day with my wife, take long walks, go to cafes, and read endlessly without feeling guilty. I can also send my daughter to school, fetch her back home. I can also watch her grow up bit by bit. This will definitely be my dream. :)

Maybe you've been talking to the wrong people haha. It's hard to talk to people about this subject unless they are open to it because money is a sensitive issue and not many people plan years ahead so perhaps that's why they frown at others who do.
