Good thing about condos is that I can't be a pack rat.
Well, some people do it - but they have reality TV for that.
I live in 550 sq. feet. I often tell people I live in a shoebox. My neighbor calls it rabbit hutch. It keeps me from ordering stuff on Amazon Prime. I almost never spend money on "stuff." Of course, it's back to that lack of job thing, too. When my parents died I had to make some tough choices about sentimental keepsakes. It was tough at the time, but I'm glad I had to make choices in the interest of space.
Bring something in, take something out. I like keeping it simple. I don't have advertisements coming at me anymore, cancelled all sales media coming in except the internet. No newspaper, no network TV, no magazines.
