The next thing you have to do is change the way you think about what triggers you in order to make a difference to how you respond.
Cause and effect is a way of thinking, a simple analogy that makes a big change when applied to daily life. The idea is that the only one who can rile you up is you; you don't have to react to what someone else does to you.
When you make the conscious decision to become the cause of your own emotions, you are effectively saying, "I'm in control, I'm the cause, I'm in charge of my state". No matter what someone does you can control your response.
