^A Dalai Lama snippet: "...if
  your mental state is disturbed, full of emotion, it is very
  difficult
  to cope with problems, because the mind that is full of emotion
  is
  biased, unable to see reality. So whatever you do will be
  unrealistic
  and naturally fail." Helps explain why so many quickly-made
  plans fail. Rational planning takes a moment and is simply
  asking a few questions: Gas in the car? Food to eat?^
