How do you organize yourself?

I was just wondering this after reading a post on a different thread by somebody that organizes himself by using a word document. I was a little suprised you could do that, but whatever works for you.

So out of curiosity, do you use pen and paper, a computer application, nothing? Do you use GTD?

I guess I don’t know what i’d do without some of my organization apps…

And I’m sure this has been asked before, but whatever.
