Personally... I would never even consider reading a self-help/motivational books. Unless of course I'd have a hidden agenda, but that is very unlikely.
I consistently noticed S types liking them... A lot. "Books about life" is what they call them. N types, however, don't seem to like them much, in my surroundings (online and offline) at least.
SJs or SPs, they like them. STs or SFs, they like them. Why? Is this "phenomena" widespread, or is it just my surroundings?
Would/have you read such a book? Why?
