I recently read the book Love Yourself As Your Life Depends On It by Kamal Ravikant, and his method is basically affirmation (plus 2 types of meditation ( 5 minutes and 7 minutes) involving the same affirmation), and he says, it supposed to be used as a mental loop for most of the day in order to really set in and work. I think it is also best to use one or two affirmations for a month or a few months at a time, but of course we can use them worded from different angles.
I am working on it now for about a week, I hope I will continue. :)
