Aristotle’s ethical means of virtue and vice but for creative work:

• Winning is the mean between moving the goal-lines to finish and not finishing due to non-constructive goal-lines
• Quality is the mean between piles of incomplete junk and one or two overwrought ideas
• Taste is the mean between copying and invention in a vacuum of influences
• Flow is the mean between distraction and idleness
• Iteration is the mean between doing it once because you nailed it and doing it once because you gave up
