Overall I've found the concept of hedonic adaption to be either completely false or AT THE VERY LEAST OVER EXAGGERATED. If you don't know what hedonic adaption is, check out the Wikipedia article or yet another one of Mr. Money Mustaches fantastically written blog posts:
http://www.mrmoneymustache.com/2011/10/22/what-is-hedonic-adaptation-and-how-can-it-turn-you-into-a-sukka/"In less fancy terms, what this term means is that “no matter what happens to you in your life, you’ll very quickly get used to it”. Hedonic Adaptation is a feature built right into your Human DNA that allows you to function efficiently in a wide variety of environments, even very harsh ones.
A most striking example of this was a 1978 psychological study that evaluated the happiness levels of recent lottery winners, and recently injured paraplegics relative to the general population. As you’d expect, the lottery winners were pretty upbeat immediately after their win, and the paraplegics were pretty pissed off. But within just two months, both groups had returned back to the average level of happiness."
Most people I know would go on crazy holidays and buy insane cars after winning the lotto (not me though) sucking up all their cash after the 2 months and returning to a normal life (yet with a fancy car at the end of it) thus in my opinion explaining why they return to normal happiness, they return to normal life. As for the now wheelchair confined people, I'd say they are just trying to make the most of what they still have thus are lying about how they are really feeling and forgetting or blocking out the past that can't be changed.
Now in saying this I'm not your normal everyday person, I'm VERY abnormal actually and there is NOBODY else similar to me in the world that I've ever come across. For me however hedonic adaption doesn't exist nor do I suddenly find myself in a bad mood without reason. I also don't believe anti-depressants do anything because, for me, it's not about chemicals in the brain determining my mood. Note that I've never had anti-depressants so technically no, I don't have experience there but I find the whole idea of a tablet making you happy absolutely ridiculous because mood for ME is dependant completely on the state of my life. For me, my life hasn't been great but it also could have been a LOT worse. Thus, my whole life I've hated being alive. But the light at the end of the tunnel is retirement and it's the only thing keeping me going.
Anyway back to the point... If hedonic adaption exists (and effects everyone) then what is the point of retiring at all, ever? The point of life is to be as happy as possible, right? Doing whatever things we like that make US happy. According to the theory of hedonic adaption, a person would retire, get a thrill and rush from it, then after 2 months return to the same level of happiness that they experienced during their working years. FOR ME, having to work (I hate my current job but I hated my previous job even more thus I'm happier now than I was) to survive is THE REASON I hate being alive. I'd rather live in a $50,000 Broken Hill, NSW property with no job and a small $200 per week passive income to support myself than a $5,000,000 mansion in Sydney by the sea if it meant the difference between working and not working. That's why my whole life at present is based on building a passive income in order to retire and finally start enjoying life.
If I had to rate my life at present from 1 being on the edge of a cliff about to commit suicide to 100, being as happy as if I was in heaven (not that I'm religious) I'd rate it around 23. The worst time in my life was the later highschool years coming up towards the HSC (the big test that I was told determines the rest of my life). Back then I'd rate my life as 4. I used to have terrible nightmares every night of my life from as early as I could remember to 2010. A creature would come and kill me over and over again (and yes I felt horrible pain in my dreams when it bit me, so I do feel pain in dreams unlike other people) every night until I moved to a new house. The day I moved to a new house was the day I stopped having those nightmares and thus, my quality of life at that point permanently went up by 10 on the scale. There was no adapting there... my happiness of not experiencing those painful nightmares has lasted but the rest of my life still sucks...
Same goes for my job. I used to be in an awful job for over 3 years with very abusive people and that job was worse than my school years where I got bullied on a daily basis and stressed out about tests. From school to work my happiness level went down and stayed down. Now however I am happier and remaining happier that I'm no longer in school or that other terrible job. There is no adaption there whatsoever.
Same goes for my love of computers. My first computer and monitor I hated back almost 2 decades ago. It was better than nothing specs wise and what I could do wise just wasn't good enough. I continued to get more and more expensive computers and monitors every 4-5 years until 2014 when I was finally happy with what I got because technology finally caught up with my expectations. Unfortunately the particular specifications in 2014 cost close to 10K but from there they can only get cheaper as better spec systems come out and push down the price of my current spec computer. There was no adapting there, I honestly was always disappointed with computers until I got my 2014 build and now I'm going to continue to buy the same specs every 5 years and watch as it gets cheaper every time (obviously there will be a point where I can't get my current specs so I'll just buy the cheapest reliable system at that point in time). There is no adaption there... I've always had expectations of computers and that expectation took almost 2 decades to meet and now that it's met I'm happy. NO ADAPTION EXISTS FOR ME!
So my question for the general population that seems to suffer from hedonic adaption is WHY do you want to retire if no matter what happens you will always remain at the same level of happiness in the long term no matter how much freedom early retirement gives you. Do you all suffer from hedonic adaptation or are some of you like me actually completely immune from it? Does it really exist at all?
