I've been a productivity geek for years. I own (and use) a label maker, I have a shelf full of books on the subject and my iPhone has more podcasts, apps and ebooks on productivity than I care to admit. But there is one resource I come back to again and again. The youtube video of David Allen speaking at Google. I wouldn't say it's the most inspiring talk ever but there are some real gems that reveal themselves to you especially after you've been doing GTD for a few years. I think his control / perspective matrix is genius. The big insight for me is too much control can put you out of control. The first time I read his book, Getting Things Done, I watched this video and thought I understood his point. It wasn't until about a year later that I realized I was missing something. I began to notice that I really dreaded doing the weekly reviews, they were time consuming and left me feeling more stressed. Too much control put me out of control. What I needed was a healthy does of perspective.
Enjoy the video!
