The given list of dangers of early retirement includes:
1) Oops, you change your mind.
2) You run out of money.
3) You lose touch with friends and family.
4) You may find it difficult to start your own family.
5) You lose your own self-respect, and the respect of others.
My comments are:
1) Really? Really? If anyone would prefer to be told what tasks to work on and how to spend every moment of the day, than to make those decisions for himself, I think he may need some serious psychological intervention or at least some serious introspection regarding his life goals.
And if anyone is free to do whatever they want at work, then more power to him - - but is that really work? And is he really doing what he would do anyway, without earning money for it?
2) This is why we run FIRECalc, check, doublecheck, and build some slop into our retirement financial plans BEFORE retiring.
3) Why lose touch, when you have more time to stay in touch? This makes no sense.
4) More difficult to start your own family? When you have all day and all night of every day and night, to work on procreating? Of course, one would put aside money for raising and educating the children, just as a working person would. Maybe he means that the only possible way to meet a spouse is at work, but many people make a policy of not dating others at work. I never dated anyone at work. Mixing work and romance can be pretty explosive IMO.
5) You lose your own self respect, and the respect of others? I think others have a huge amount of respect for those who are truly FI at an early age. Sure beats being a bum dragging himself to a dead end job 9-5. As for self respect, again this sounds like a person who needs some psychological intervention. Why would setting a challenging goal, working towards that goal, and achieving it years before most people can do it, be a detriment to one's self respect?
OK, those are my thoughts on his list of "dangers". I think the author had a deadline to meet and didn't really think through what he was writing.
