Bruce didn't learn to become an Olympic-class fencer by picking up a sword and thrusting around on his own, nor did he learn to be a pilot by just wandering into an airplane one day. He should have looked at writing the same way.Like all works done outside of the subject's main profession, it should have had more outside help. Should've been written by Bruce, re-written by another writer with experience in the genre (who could also interview Bruce further and turn those interviews into prose).
