Well what we found out was that he just didn't know where to begin. As soon as we started, he would voluntarily help. But it literally took us starting for him and promising that anything that looked like it had meaning (my dead grandmother's things that he inherited, or things that were made by his friends) we would keep...

It made it even easier on him when I showed him an item he was almost sure we had thrown away.

All I can say is see if he's interested and then convince him to at the least have a yard sale...
