I don't see this book as a step-by-step guide to helping eliminate procastination, but more as a collection of tips that you can use to help you to plan your tasks better and to organize your life. I think it is worth having on hand to remind yourself of different ways to approach whatever task you are putting off accomplishing. If you are looking for an in depth psychological explanation of why you procrastinate then this probably isn't your best bet.
