Book excerpt: Zen To Done (ZTD) is a system that is at once simple, and powerful, and will help you develop the habits that keep all of your tasks and projects organized, that keep your workday simple and structured, that keep your desk and email inbox clean and clear, and that keep you doing what you need to do, without distractions. This book was written for those who want to get their lives organized and actually execute the things on their to-do list by changing existing habits. And let me say that changing your habits is possible. Using the habit-changing techniques I describe in this book, I have made many habit changes: I quit smoking, started running, started eating healthier, completed a marathon, doubled my income and got my finances in order, have almost eliminated my debt now, completed a triathlon, lost more than 20 pounds, and started a successful blog, and more. Read this book. You'll be amazed at what you can accomplish with this productivity system.
