I think I said LBYM-FIRE-style, because we hit FI around 50 and are currently at a 40-50% savings rate -- but damn we spend a lot of money. I have zero desire to be MMM -- grew up poor and so had to DIY everything/live on a strict budget by necessity, and even all these years later it brings me pleasure to have someone else clean my house for me (seriously, sometimes I feel like doing a little happy dance because I do not need to scrub the toilet). OTOH, I also have no desire to keep up with the Joneses and get much more happiness from knowing I have a big 'stache than I do from spending money.
I am in it largely for the badassery -- I succumbed to lifestyle inflation and the ease of outsourcing everything, and I like the reminder that I am capable of handling whatever needs to get done, that I do not need all of the luxury to be happy, and that it is not healthy to have everything you want when you want it. Except housecleaners, of course. :-) One of my coworkers just gave me one of those name things you put on your desk, like you see at the bank. It says "unfuckwithable." Highest praise I can possibly imagine, and I am ridiculously thrilled and feel like a total success.
FWIW, hedonic adaptation is really, truly, a thing. I have two happy places in my head: hanging off the West Caicos Wall at about 90' down; and on the chair lift at Taos with the ridiculously blue sky and white snow. But you know what? I am not overall "happier" than I was before I could afford all of that.* I am 100% confident that had DH never introduced me to skiing and scuba diving that I would have found other places and things that brought me that same feeling of inner peace -- because that comes from within me. Heck, I can almost get there sitting on my back deck on a perfect early fall evening with the fire pit going and blue time overhead.
So, yeah, I am all about spending money on "experiences" that bring me happiness. But I could have achieved the same level of happiness for a metric shit-ton less money if I had never taken up skiing or scuba diving and spent that time exploring cheap/free fun stuff closer to home.
Now, I am in no way an anti-consumer purist, and I do believe some "things" can bring extra happiness. I truly cannot imagine being quite as happy on a daily basis without my StupidCar. I love driving with the top down, I love the feel of downshifting into the corner, I love the sound of SportPlus mode (especially when the engine does that little blip when the revs drop), and I lovelovelove the security of knowing that my own "oh shit" level is maybe 10% of the car's. But, (a), I wouldn't have enjoyed it nearly as much if I hadn't waited until FI to get it, because I would have been conscious that this "thing" was interfering with higher-priority needs and wants (e.g., kids' education). And more to the point, (b), the list of "things that actually bring you happiness" is way, way shorter than the list of "things that you think will bring you happiness." I can tell you from personal experience that the thing that brings the most happiness and contentedness in life, beyond a happy and healthy family, is knowing that you don't need this shit and can walk any time you want to. All the other stuff is just the cherry on top of the sundae.
*Well, I am, but it's not because of the fancy stuff I can afford to do. It's because I no longer have sufficient fucks to spare about a lot of the stupid stuff I used to get so worried about.
