Once you've cleaned out that drawer, every time you open it, you're going to smile, because all that's in there are things you need, and finding what you need will be easy. Take that happy feeling and repeat that exercise in your medicine cabinet, or that hall closet all the crap falls out of every time you open it, or the junk drawer in the kitchen. Or even (gasp!) the garage. Once you get started, you'll find it difficult to stop. You'll realize just how little of the stuff you own you actually need.
And here's another thought... couldn't somebody really use that winter coat in your closet you don't wear? Wouldn't somebody really like to have that old chair in your garage? You know, there's an organization that sends old cellphones overseas to Vets serving our Country--and you've got several collecting dust.
It's often said that less is more. It really is.
