I enjoy my house, and my things, and use them often. I enjoy my home life. I still feel the need to go out and experience the world beyond my tiny bubble. I get great joy simply out of breaking up my routine, meeting new people, seeing new places, going to local gathering spots. When I am done with all that I also have the benefit of socializing without having a pile of dishes to do either.

Your assessment is right for some people, and you probably have contact with a group that leads to a bias in believing this is what people, generally, who need to do things beyond their house, are like. It is not true for most though. Most people like their homes, and home lives, a lot. They also feel the need to go out and do something other than home life, regularly, in order to be happy, in the long term. Doesn’t matter how awesome my house is, doesn’t matter how many skills I am working on, or how many hobbies I have, if I don’t do something out of the ordinary, on a fairly regular basis, life begins to feel dull, and no amount of improving my home will alleviate that.
