I just read a book about this called Flow. Sadly, reading the book didn't put me in the state of flow. What a waste of 200 pages. Wee now I can recognize it when I'm in it. Almost cool, but not quite. Play alot, eventually you just start to flow and can play well without even trying to. Here's my advice: Don't read a book on how to flow. That just made me think about flow all the time, and when you're thinking about it, most likely you aren't flowin.
