No i dont think Zodiac has anything to do with it. I think its all about your upbringing you seeing how others deal in situations play a part on how you'll deal in situations. I try to stay as calm as possible.
I use to get angry real fast when I was younger. But I learned to control that when a friend pointed out to me how silly and dangerous it was. I am a very calm person now and it takes alot to get me angry, although when I get angry it's bad.
