" If you get caught up in things over which you have no control, it will adversely affect those things over which you have contol." - Advice to John Wooden from his father
You know it when you feel it. The momentum is shifting the other way. But remember -- that is just a thought. It does not have to be a self-fulfilling prophesy. Momentum is just a few poor actions that lead to a negative mental shift that in turn leads to more poor actions. You can turn it around because you can control your thoughts. If you want to stop momentum focus on positive thoughts, which will lead to positive actions. The old saying holds true that "the team that loses its poise will probably lose."
