Regarding having trouble getting rid of sentimental items or items you may need one day (WHAT IF???) the thing that really helped me was reading the bookClear Your Clutter With Feng Shui
by Karen Kingston. This book is SO GOOD I want to give it to all my friends.
It's a very quick read and by the end of the first few chapters, I felt movitated to get up at 9pm, energized and start throwing stuff out. Her bottom line is that clutter stagnates energy in your house (and life) and if you start clearing the crap you don't
you allow BETTER things into your life.
Really, if you haven't used item X in 2 years, you really don't need it.
There are stories in the book of how people cleared their clutter and got raises, new business opportunities, etc...
all on his own (doesn't like my new agey self-help books
: ) got rid of 3 black garbage bags of old T-shirts.
Neither of us had any idea of many T-shirts he had! We gave them away. Three weeks later he got a job promotion and a raise.
Anyway, I've tried method books (and they were UNinspiring and thus, useless to me).
1. Focus on your crap first.
2. Talk to DH and tell him he needs to put all his crap in ONE spot (one desk) rather than ALL OVER the house. I am the paper horder in my family. You sound like my DH. Poor you. Poor him. The clutter everywhere drives my DH insane. My "solution" is to have "my own" desk that he can't touch. That way I don't get mad at him. Of course, he still gets mad at me. Tough cookies. It's MY desk.
You also have to understand he will never change. Some people like piles... I learned this in some personality class. We say "well organize it" and we never do. So the best thing to do is control it/limit it. Let him have his piles, just not all over the house. That's not fair to you.
Feeling overwhelmed? Me too. (In fact, I'll be decluttering my office this afternoon.) I'm taking FlyLady's advice that says to start small, little every day and then it will get better!
