Anybody who really knows about the TV business knows that it would be impossible to just march in one day and say to your colleagues and bosses 'Oh yes I'm hosting my own show.'
The best plan now is to have as many bosses as possible. I call it boss diversity. If you work for a company and you have one boss and that boss doesn't like you or wants to get rid of you you're in trouble. But if you work for yourself you have lots of bosses who are your customers and if a few of them decide they don't like you that's okay.
