I haven't read the book, but I strongly suspect that it doesn't suggest that we are finish, or that we rest on our laurels.
Feeling good about progress made thus far is an excellent way to provide the motivation necessary to push forward even harder.
The laundry one is also good, because I hadn't already heard of it :)
