Will Future You curse Present You when that headache you thought was from staring at the computer screen and work stress is actually stage IV cancer and now you don't have time to hike the PCT? Or, more likely, Future You is one of the many who simply becomes less able to do a loved hobby and there are regrets..."If only I had quit 5-10 years earlier. I didn't really need the money but I sure did love riding horses."
Living in fear can also cause regrets.
Oh, ITA (which, in fact, is why I bought my highly unMustachian StupidCar this year, because what's the point in having an awesome toy if your knees won't let you drive a stick shift any more and your back won't let you get in and out?). It's always a balance.
I am not actually advocating for a specific outcome. My point is more that the natural order of things is to prioritize current wants over future wants. We tend to think that we are immune to this very human trait -- I mean, aren't we all here because we are putting our future needs over today's wants? My concern is that our optimism and belief in our own ability to delay gratification may give us a false sense of confidence about our ability to predict what FutureUs will actually need.
Think about it this way: a normal person is going to choose 2017Me over 2032Me -- they are going to buy a house and a car and go out to eat a lot, even though it means they will need to work until 2052. Ergo, their choices are fun for 2017Me-2032Me, but screw over 2033Me-2052Me. We, OTOH, think
a lot about 2032Me, to the extent that we frequently tell 2017Me "no," because 2032Me is more important. That
feels very much like we are awesome at delayed gratification -- like we naturally prioritize the future over the present. Because we do it every day!
But when we envision FIRE, our focus is basically on 2032Me-2052Me -- that "early" part of "early retirement," when we are FI and still young and fit and can be active and do all the things 2017Me is looking forward to. That is a very limited future that we are focusing on -- and one that is built around what 2017Me wants ("dammit, I reallyreallyreally want to hike the PCT, I can't
wait until 2032Me gets to do that!"). And that focus on 2032Me-2052Me also means that we don't necessarily think about 2062Me, or 2072Me, or those other FutureMes who will no longer be able to do all of that same awesome stuff that 2017Me is so looking forward to. So we
feel like we are delaying gratification for the benefit of AllFutureMes, when in reality we are doing it for the benefit of NearFutureMe and not even thinking about DistantFutureMe (beyond simply assuming that DistantFutureMe will want the same things NearFutureMe does).
IMO, it is easy to overlook the fact that this laser-beam focus on FIRE is in fact focusing on 2017Me's idea of what 2032Me will want (freedom!!!), but that that vision may not in fact be at all what 2062Me will want or need. So all I am saying is to give 2062Me a seat at the table, with all of the other Current-and-Future-Mes, and try to figure out what s/he's going to want with the same degree of intensity and focus that you are giving to 2017Me-2061Me.
