yup, good stuff.I don't want to sound malicious here and I'm not so I hope this comes across OK.
I don't want to get angry at least not to show anger. If anyone is going to get angry I would like it to be the other guy while I remain calm and I wouldn't say composed but in control of the moment.
If someone is trying to piss you off the first thing to do is step back, step back inside your mind don't let the other person pull you forward.
Look at their objectives any leverage points you or the other person has. If they are just stating some opinion and have no leverage over you then it really means nothing and can be dismissed.
People are free to express their opinions and you are free to take or reject them. Never argue your position. Unless you want to for fun.
The best analogy is Judo or Aikido you are holding a constant tension while the other person up and down forward and back.
When you see some leverage point you can choose if you take it or not.
Is this what you were looking for?
