I had the following experience, which I considered quite useful.

I was traveling and in the meantime let a friend stay at my apartment. For this, I moved all of my belongings to the basement. After I returned, I shared my apartment with another friend. It was small and quite full, so I only took back the bare necessities from the basement. At some point I noticed that I had taken all that I needed from the basement, and that the rest was mostly unnecessary. So every once in a while I go to the basement to take out some things and throw them away.

The good thing about this approach was the following: Don't go through your stuff and think what you can throw away. Assume that you want to throw everything away and pick what you want to keep.

It's much easier to decide to keep something than to decide to throw something away.
