I have to say this forum has been an indispensable encouragement. (I found it...and therefore GTD...by accident.)
My first 'bout I tried to do too much digitally. I am now down to a paper note taker...which I keep with me. some spreadsheets and a couple of dedicated file systems. It would be great if I could integrate it with my contact manager. However, organizing it an keeping it going is an issue. For right now I am trying to be as lean as possible.
