If you've never seen/heard Ira Glass' "This American Life," then you're missing out on some wonderful, captivating, human stories. Both are available on the website, and I wholeheartedly recommend taking even five minutes to watch or listen to something.
I found this video linked via Danny Gregory; it speaks to the fundamental frustration of all creatives, not just those in broadcasting/TV as mentioned. If you've ever been disappointed in a piece of your own creative work and constantly feel yourself falling short, watch. Please. It almost made me cry because it's so true.
