Rage causes loss of focus and careless mistakes. A great way to remove anger and increase your ability to perform as a gamer is through the removal of expectation. Removing this is not an easy task, but the following will give you the tools to succeed in learning this skill.
The Expectation Decoupling
Has there been a time when something didn't go as planned, when something didn't go as expected or a team that abided completely to the definition of noob? What I've come to learn is that expectations are the gateway to anger. They are tricky as it's second nature to have these thoughts. I believe where the real avoidance of anger lies is in the acceptance. This acceptance comes before and after the match. In that this acceptance is not born of defeat, but of clarity. By accepting this it frees up the mind of doubt, anger and frustration. Instead, this energy is used to focus on what to do in order to bring out the win. Getting to this stage of acceptance is something that comes with practice, consciously grounding the expectations so that it can't make a bad situation worse.
It than becomes a fight of reminding before and after the game that this is merely noise. Similarly to how a picture is made up of millions of dots that when looked at closely seemingly have no meaning. Much like farming or landing skill shots, this only comes with practice. I can't say exactly what will create this attitude of acceptance and clarity. More in that I'm not a mind reader and as I've said before, there's no a-b-down-right-a cheat code that... TA-DA instant acceptance. It's more that I can give a goal for anyone to work towards. Much like working toward having 80 farm at 10 minutes.
Why Accepting works
At the very core, it removes any illusions a person may have of their standing. We can think of this as a ground- up approach. If we think of ourselves higher than we actually are, and reality comes around and slaps us in the face, we are negatively affected. A person that is grounded cannot be affected by any external changes, be it from a stock market crash, to a 5 game losing streak. Similarly, it's about accepting that a 5 game winning streak does not mean you're unstoppable. Merely that fortune was smiling on you for those 5 games.
More On Fortune
Fortune is closely related to expectations, as this is what expectations are born from. It is an external affect that determines if one gets good or bad teammates. In that we can consider a poor person un-fortunate and a rich one fortunate. We can beat fortune through acceptance, it than becomes as if one is watching a video and commenting on it. It no longer is, "why the fuck did this happen to me?", but that of, "Oh this happened to me".
Expectations, Acceptance and Fortune
By accepting that fortune can be a bitch, one removes expectations from ones thoughts. As it no longer becomes a struggle to push those ideas away. In that it is now a funnel for improvement, problem solving and enjoyment.
