Deanna Hoak has posted the text of an interesting writing chat with Jay Lake, in which Jay shares some very lucid advice for approaching writing the same way one would a sport or martial art, working out different sets of muscles, and the need sometimes to start over when moving to a different skill set (short form to long form, editor to writer, etc). Jay's got a tremendous work ethic, and his advice here mirrors my own experiences (first doing a short-short story a day in my mid-twenties, then doing longer stories one a week later on, then a few novels a year sometime after that). Well worth checking out.
