My son-in-law just joked that he found many hours of DA audio content in my car's CD holder. It's true! I have the following material from Davidco:
*Getting Things Done (2 copies as I wore out the paperback so bought the hardcover)
*Ready for Anything"
*All the GTDConnect audio
*GTD CD Set
*Ready for Anything (CD)
I enjoy learning and DA is a big part of my ongoing personal development.
