I tend to let the Composers Datebook podcasts pile up for a while on my iPod (each one is only a couple of minutes long), and then I listen to a bunch of them. I always learn something.
The composers presented on Composers Datebook are all excellent composers, but listening to the podcasts end to end can be terribly intimidating, particularly when the American Composers Forum discusses current successful composers (and there are some that seem to come up repeatedly). I know that I lack many of the commerce- and commodity-related skills a person has to have in order to be a successful composer, and for most of my writing "career" I have measured success in terms of how pieces I write sound, and if they are vehicles for people to express themselves. I'm not good at selling myself (even if I try), and am not very good at doing the kind of networking that is necessary to get pieces performed. I could even say that I believe that one of my strong points is not to be intimidating. But that means, in this dog-eat-dog world, that I am a good candidate to be on the receiving end of intimidation: to be intimidated.
Perhaps it doesn't matter. Perhaps that podcast is geared more for consumers of music (i.e. people who don't write music themselves) than it is to composers.
Intimidation is different from inspiration. For me nothing inhibits creativity like intimidation.
