This was a wonderful book. I had not read the author before, but he was suggested by another blog. I couldn't have been more happy with my purchase! The book was well thought-out and well-written. It did a great job of providing concrete steps to becoming more consistent in your daily life.
It was written often from a Christian perspective, and if you are a Christian (which I am not) you will probably connect even more with "The Art of Persistence". That component of the book was not evangelical but informative. It didn't take away from the book if you are a non-Christian.
If you have any trouble staying committed to something, being focused and wanting to accomplish whatever it is you want to accomplish, this book is for you. It also introduced me to a free website (Coach.me) that I would have paid for so the price of this book is really low for what you are getting! Thanks Michal Stawicki!
