The author of The Practicing Mind: Bringing Discipline and Focus into Your Life expounds on a few points very, very thoroughly.

A beautiful point I took away from this book was that when you perform an act slowly by carry out its steps one-by-one with full attention, you are able to accomplish it faster than you would have had you rushed through it.

On the other hand, the book’s repetition was detrimental in a way as you lose the ‘present mindedness’ and drift off in your internal monologue (something the author is encouraging the reader to free him- or herself from).
