How does "calmness" work? Calmness in this context means that a person has an easy-going view on life, is likely to be free of stress and whatever you feel when there's chilly wind in a fall evening and you're sitting feeling tranquil (tranquility sounds like a good word)

I'm just like that (although people often tell me they think I'm feeling something else) and I wonder how does it work?

Another point of interest to me is what separates true tranquility from x-induced tranquility? I had a conversation with a coworker and she said that people who use this-and-that to feel better are trying to escape/deny something. I half-agree with it because it does make sense (although that feels a little bit like substance abuse) and half-disagree because I don't want to make judgements. I've smoked some but were also drinking alcohol at the same time and was told it's "the same high" so I don't know how smoking feels (or know how it feel, or maybe it depends on what you smoked, etc. My sample isn't exactly impressive.

So, my questions are: What makes people calm & cool? (tranquility is a way to describe it) What separates people who are naturally calm & cool from those who use other methods to achieve it?

Oh, and how stupid is this question?
