Although I generally do not listen to that many business books, at the start of every year, I pick a business title (usually dealing with organizing or time management) to motivate me to clean up my life both literally and figuratively. David Allen is a well-known consultant and executive coach who works on helping people organize and become more productive. I loved his simple ideas on how to manage the never-ending To Do list. I also liked his altitude analogy on life - looking at your life from the 50,000 foot level (what do I want to accomplish in my life) all the way down to the runway (what I am doing right NOW). The book was so good that I not only listened to it in audio, but purchased a print copy to help me implement his ideas. OK, stress-free productivity - here I come!
