I love to read self-development books. I even love to read them more than I like to read fantasy or any other kind of book. The reason for this is, I suppose, that every time I read a book like this, I feel instantly motivated to get my sh*t together and apply the knowledge I just learned.
Naturally, I have some favourites. Not all of them were eye-opening and I can‘t even remember what some of them were about. Nevertheless, there are some, that I think were great and you should also read them. They are not very long or hard to read, so that‘s a plus.
