"one new idea"
I thought the main new idea, to me, in this book was the concept of doing the thing that could make the biggest difference FIRST THING. All the other advice about planning was too much for me. I don't want my entire life planned out in advance. However if you, like me, are a procrastinator, try picking the thing that will make the most difference toward your goals each day and do it. I tend to do a bunch of easy, probably less productive things before I tackle the one I've been dreading. I didn't need to listen to the whole book to get the concept.
