I personally learned a lot from "First, Break All the Rules: What the World's Greatest Managers Do Differently" (ISBN: 978-1531865207). The key idea is to not try and change the basic nature or capabilities of any person but to give them tasks that help them showcase their natural strengths. This may not always be possible.
I have found this idea to bear out in my experience. If you try to make a cat bark, it will result in a lot of frustration for both you and the cat. Personal growth and learning is a long, difficult journey and you as a manager can only give ideas or hints. You cannot mold your reports' nature or style of working.
