Of course you would want to be that person - but that doesn't actually mean you get to be that person. You have to be able to handle the negotiations so that happens and a lot of times a new personality just getting a TV show doesn't have the clout to be able to pull that off. Television and movie producers are not generally very adventurous - they want to sell something they know will sell, which is why we see so many shows and movies that are basically just like every other show and movie out there, but just slightly different. This is why it's good to learn the business side of show business. Someone who is super eager to get a show might let the executives pull some crap that a more experienced person wouldn't.
