I came across a page on the Aquarian Drum Heads website that is essentially archived articles written by Roy Burns, drummer for Benny Goodman and Lionel Hampton, among many others, and while most of the articles are written from a drummer's point of view, I began to realize that most of the things he talks about can be used by any musician who works with other musicians.
Anyway, there are some real gems of advice regarding professionalism, your attitude, dealing with mistakes, practice philosophies, etc.

I wasn't sure where to put this. I didn't think that it really belonged in the Lounge, but at the same time, it's general musician discussion, not so much general trumpet discussion. Anyway, if you thinks that it should be somewhere else, please feel free to suggest it and I'll see to it that it gets moved.
