I waited entirely too long to get settled. I didn't really understand the value of "home" until my thirties.
I used to be a hardcore "minimalist" throughout my twenties and into my early thirties. I didn't want to own anything at all, didn't want to have objects or things that I'd have to move, that could tie me down to a space or place. I didn't want to have to fix or maintain anything.
In my thirties, I realized that all of the spaces I had lived in were cold, unwelcoming, aesthetically anemic. It didn't look like anyone "lived" there. At 35, I started buying things I wanted to keep forever: bookshelves, living and dining furniture, rugs, art. I spent good money on "stuff" that I liked, things that I want to experience and live with every day. I purchased decent picture frames and hung photos of my family for the first time.
I also spent a lot of time setting up my living space for other people, not just for me. I could invite family over and they could stay comfortably for weeks at a time. If a friend needed to quickly get out of a tricky situation, I had a spare room ready to go. If I wanted to host a small dinner, it could happen at my place, instead of a friends house where a bunch of grown-ass adults are sitting on five-gallon buckets and yard chairs around a folding table.
All of this had a strong, positive affect on my day-to-day disposition. It made me more open to others, more willing to embrace hospitality as a mode of living. I'm less stressed about having people over because my place is actually a place people want to be, and that feels great.
It's difficult to put this into words, but for the twenty-somethings who are reading this: whether you are renting or owning, don't be afraid to settle. Buy nice stuff when you can afford it, take care of it, plan to keep it forever. Set your space up to support you and the people in your life.
