Too much good stuff

Once again, time to organize. The problem is, I've decided I have too much stuff.

This is under my work table where I'm suppose to be able to put my feet. The box on the right is my soldering supplies, on the left is my antique typewriter and the middle is where I store my ink pads and what I use to carry my supplies to class.

Baskets and baskets of (really good, important) stuff...? What is in there?

The top of the closet. I need to part with some of this! I've collected for years and I'm sure it's good. Right?
