Great article! It reminds me of a beautiful excerpt I recently discovered that might make you feel better about all your unfinished projects:

  Leaving something incomplete makes it interesting, and gives one the feeling that there is room for growth.    Someone once told me,  "Even when building the imperial palace, they always leave one place unfinished."  In both Buddhist and Confucian writings of the philosophers of former times, there are also many missing chapters.
