I would say that nobody is going to work harder for your career than yourself - the one with the vision. No matter how many people you hire, nobody is going to get is as much as yourself does. So it's really important to be your own leader at all times and not hand it all off, otherwise the whole empire will fall apart.
People ask me if there are going to be stories of Harry Potter as an adult. Frankly, if I wanted to, I could keep writing stories until Harry is a senior citizen, but I don't know how many people would actually want to read about a 65 year old Harry still at Hogwarts playing bingo with Ron and Hermione.
