You've heard the saying "Study long, Study Wrong".... this is true on many levels. Especially when it comes to preparation for anything that is involves solving a problem. The 7th Law of Preparation is perfection is the enemy of great.

Too many times I've seen people or heard stories of people not fixing a problem due to information overload or just the sure fear of being wrong. Work to find 80% of the solution and then execute. The faster you find out the solution doesn't work, the faster you work to fix what didn't work while keeping what did work in play.
