How Do You Balance Your Collection And Clutter?

Yirmeyahu,
We like spending more time doing things with the kids and the clutter builds until the wife or I say enough and plow through it all. Unfortunately you can work on the clutter in only one area at a time. Nobody is going to care in twenty years if I left a stack of stuff on my desk a little longer. At least I am not planing to have any aggravation about it. Luckily the wife's level is shorter and mentions something before it burys someone.
