Clearing Stuff out all the time

I’m always amazed by how much ‘stuff’ I manage to collect and then have to clear out. I seem to be in a perpetual state of getting rid of stuff, and constantly wonder why I bought or acquired this, that, or the other.

I always try not to buy stuff when I think I don’t need it, but even so I’m always getting rid of things and wondering why I ended up with them in the first place!

How does that work then?
