Spring Clean

Without sounding like a new convert to a cult, I have to say that "How to get things done" by David Allen has had a very positive effect on my office comfort. For the first time no crap piles of stuff hanging around. I haven't got beyond skimming the book yet! I implemented the preparation stage; why do I keep this object or paper, can I label and file it or not? I am astonished that it has taken until nearly 50 to grasp something so simple.
