Understanding of "The Self"

From my understanding the self and mind are one and of itself. The self is how one operates on an individual level. For example, the way one brushes their teeth, the way one eats, the one carries themselves as they walk. It's a preconceived setting I believe we are created with that develops over time. I believe that we were created a specific way in order to play a specific role in the society that we live, I guess to say that none of us are at random but play a very specific role in each others lives. Also I like to think that our experience here on earth helps develop our "self", to say that the self is just way to distinguish us as unique and something that helps us stand out on an individual level. In summary "The Self" is a guide for us and helps us react in a specific way to any all experiences we have here on earth.
