I purchased the ebook because of the size of the two volumes for this book (428 pages total). Since, there are over 60 habits covered at 6-8 weeks for each habit, it will take over 10 years to cover all the habits. This is a two volume set that you are going to be working through for a long time and it’s nice not having them take up the shelf space, as you are only needing a small portion of it at a time. I am printing out only the section that I am currently using and putting it in a notebook with our current work. I do not feel overwhelmed like I would with a huge book out in front of me, finding our spot, etc. It is perfect to be able to print out just the habit we are working on and focus on it. It makes it a manageable amount for us and gives us a sense of accomplishment when we finish with it. It will be easy to make a notebook of completed habits or include it with the portfolio for that year.
I have never been an e-book fan, but I am of this one. I like holding a book and looking at real pages, but I am re-evaluating that mindset as the e-book format works well with this book for us.
