My take on this, after 2 1/2 years here, 1 1/2 as a serious daily player, it is this, you must apply all of your gained knowledge throughout your advancements. You must be on top of your game at all times. You must be cognizant of all interfering factors as they present themselves. Your attention must not waver for each and every shot. It is a video game, but to be good and to get good at it you must follow the same things as you do in your daily life to succeed here as you do in your real life experiences.
You may never attain the top of the heap, but to do less than what is necessary means you will only be marginal, and who really wants that. My take. my nickle.
