Managing clutter?

How do you manage clutter? I've noticed that a lot of the decluttering literature relies on looking at feelings about things.

I was always a messy kid, and both of my parents were messy kids too.

I think I hoard accidentally - I just don't know how to manage my own stuff, and so it accumulates. I generally only notice it when stuff is spiralling out of control in other areas of my life, and it makes a convienient distraction - collecting up all the tissues and putting them in the bin is easier to do than 'all the other stuff' - both in my life, and in my home. It's like a 'quick fix' feeling, if that makes sense. If I ever controlled all of the tissues and clearing out my 'floordrobe', I would probably find there's some stuff that I do have problems with throwing out.

Thanks for any ideas.
