You're at close quarters with problematic personalities for long periods of time. The thing you need to realize about television is that it's target marketing. If the target is children, you'd better write children's television. If the target is women 18-34, you have to give them what they want. I have one friend who always finds out if the EP is happily married before he signs on staff.
Many people ask about pitching their ideas or even pilots for a show.
Remember, it takes both a good idea and a proven ability to run a show to make a complete pitching practice. I encourage new writers to write pilots but for the learning experience of it, not for the hope of selling. I've got a bunch of screenplays I haven't sold. Several should never be seen by human eyes. Others I quite like and still have hopes of selling.
