From High Achiever to Successful Leader

What do you do when you reach a new level of success in your career, you got the promotion you were striving so hard for, now you're a leader, only to find that the people you are leading are jerks? Well, not really jerks, but sooo frustrating to lead, how on earth can you get the productivity from them that you need to deliver on your new KPI's? You would succeed in their role if you were the one doing it so why can't they? You try everything you can think of that would motivate you and even that doesn't seem to make much difference.
