Yes, you hit the nail on the head. I don't think we could retire with the assets that we have if loving the outdoors wasn't a part of the equation. Many of the things that provide us with entertainment cost the price of gas to get there or the one time purchase of equipment that will last many years. Our best times are hanging out on the beach, hiking, paddle boarding, taking out the bikes etc..
I like your idea of selling everything and being flexible. This is something that we will have to consider. We do like our house a lot but it's always something we could rent on Airbnb and come back to later.
I can also see how people would question our $3300 monthly expenses of if we lived more of a conventional lifestyle. Someone pointed this out to me on another early retirement forum. Many retirees hire people to landscape and mow their lawn, plow their drive way, have 100's of unwatched channels on cable, blast the air conditioning in the summer months, leave the TV and lights on when not in use, go out to breakfast, lunch and dinner several times a week. For entertainment they have time shares, go on cruises, play lots of golf, have expensive boats, doggie day care
etc.. All of this stuff adds up quick. Nothing wrong with that lifestyle if that's what you enjoy but we live much differently.
We actually enjoy planning out and preparing our own food. I like landscaping and doing my own plumbing. If I had the time I could probably put a roof on my house. I've already painted the whole thing once. I can do most maintenance on my cars and we'll drive them to about 200k miles.
I think if you enjoy the outdoors as your entertainment, you're not wasteful and try to enjoy the process of doing things, you don't have to spend a lot. This is how my wife will retire before she's 40 years old.
