Forex preparation (2)

"If you fail to prepare, then you are prepared to fail" - John Wooden said. For those who do not know who he is, here's a brief summary:
John Wooden is considered by many to be the greatest coach of all time. He has won 10 national championships in men's basketball. Wooden is not only famous for his victories, but rather for his approach to basketball and life in general. He was always prepared and paying attention to the smallest details, no matter how insignificant they looked.
An example is how he taught his players to be shod socks properly. That's right, even wanted them to put thrm in a specific way. The reason? He did not wanted any creases, which can cause blistering and potentially injure his players.
Wooden felt that a man should give all of himself into anything, and this part is always the first thing, that is under his control. Wooden so always came prepared.
Surely these principles can apply in forex trading. What habits must we develop to be prepared?
