The other day I had a few minutes free. I used it to trash more than half the stuff in my top desk drawer. I thought it would be upsetting, but it was more liberating. I now have about a dozen pens that I like and that I bought. All the rest (and there were many) are gone. I don't care how cool they looked or where they came from, I trashed them. Same with stationary I never use and a bunch of other stuff. Some went into my suply cabinet. Some got filed. The rest were trashed. Try it, you'll like it.
(I even spurned a free pen this weekend! They were handing them out at a theater to fill out a form. I shook my head and pulled out my Fisher Space Pen, ninja style. I almost didn't believe it was me.)
