People management

I wonder if in a not so distance future people will have personal managers like people have personal trainers. If you are willing to have someone help you train your body why not have some help you manage your career and your life. Most of the top actors, writers, directors, celebrities and athletes have a manager and an agent or just an agent. I believe in the near future lots of executives, creators, knowledge workers, university professors will have managers to improve the percentage of their potential that will be expressed in the world instead of just staying dormant. It is just a thought  and potentially a good idea.
