Maybe I just spent too many years writing in a newsroom where you heard everything from police scanners blasting to screaming matches between reporters and producers, but I simply cannot write (or do any work of any magnitude) without some kind of music in the background. Other than that, I completely agree with all of the other points in that article.
I think it's important to remember, however, that reading all of the tips in the world isn't necessarily going to make you a great writer. Heck, you could give me books of advice on drawing, and I still wouldn't be able to come up with more than a stick figure! A big part of writing well means harnessing natural talent.
For some reason, though, everyone thinks they can be a writer... like it isn't that hard or something. Dan Patrick (the famous former SportsCenter anchor) mentioned this in his book. He didn't get it, either. And, as he so eloquently pointed out, "it's not like I watch an episode of ER and think that I can be a brain surgeon."
