A couple more things about decluttering/organizing that I meant to say yesterday:
1) You can't let an "all or nothing" mentality stop you. Even if you can only spare 5 minutes to clean 1 window, it's better than nothing. 1 clean window is better then NO clean windows. So don't get stuck in that "what's the use, it's such a mess I'll never get finished, so why bother?" thinking. Don't believe it. It's not true. Every step in the right direction is a step in the right direction.
3) There was something else, but I can't think of it now! Maybe later...
