I'm not seriously considering buying a tiny home - I've been renting for a long time, and making such a drastic change in real life would require many changes I don't want to make. Yet when I think about the distant future and retirement, my mind keeps wandering back to this option.
As someone who has struggled with clutter in the past, I have found it oddly liberating to live in a small apartment. I don't collect extra things, because I can't - there's no room. And I don't spend too much time indoors - another past weakness of mine - because the indoor area is so small.
One thing that tiny homes (or at least my personal fantasy of them) have in common with studio apartments is that they encourage us to think of our living spaces as not sufficient, and to push us outdoors. For people who constantly are looking for occasions to challenge and overcome social anxiety, that could be just the right thing!
Honestly don't know about introverts but I guess depends on how you like living some people just like big spaces even if they are introverts. But I like both small an dbig sized houses. But the huge issue is that you don't have that much space.
