How I Argue in Real Life..

I would have to admit that one of my weakness is that I tend to yell at people without hearing the whole story---something i def. get from my mother. I am a very opininated person, but I also love having long intimate convos with others as well. I tend t state what I believe and then listen actively while the person I am arguing with states what they believe. Then I automatically come back with reasons why I am right. I wish that I could accept what others say instead of always seeking a reason to contradict them. Arguing is something that i def. need to get better at esp. when it comes to my future career as a teacher. Any suggestions???
