Attitude is the driving force behind the success and failures of almost all activities.
You are only in control of yourself. Be responsible and stop trying to change other people. Realize that you are the only one in control of how you react to situations and other people.
When you get angry at others stop and think for a moment. Why are you letting that person control your emotions? Take a step back and analyze the situation – what about it causes you to become angry and make a conscious decision to not rise to the occasion.
Remove yourself from the negative environment
One thing that I find works well for me is to make a conscious choice to just walk away from the anger. Simply put … choose to not be angry. Choose to be a positive influencer for not only yourself but also your peers.
