Just came across a short video interview (5 mins) with Getting Things Done author David Allen.  In the video, he provides a brief background around how he came to productivity work,  why he wrote his bestselling book, and the one big idea that guides his life.  You also get to see his apartment in Amsterdam and his “guard” dog as a bonus.

The video is posted on YouTube at: https://www.youtube.com/watch?v=LTe1pD71Hlk&feature=youtu.be

Enjoy!
