Whenever I'm faced with a difficult choice, my approach has always been to make an estimate of the situation- a familiar military process. What's the situation? What's the mission? What are the different courses of action? Which looks most likely to succeed? Now, follow your informed instinct, decide, and execute forcefully; throw the mass of your forces and energy behind the choice. Then take a deep breath and hope it works, remembering that "hope is a bad supper, but makes a good breakfast."
