We all have them, and some of them change over time, or so we think. It has been my experience however, that our passions stem from traumas in both negative and positive ways: we tend to form preferences as emotional memories in our minds, of things to avoid and things to work towards. Because my youth was frought with fights between Mom and Dad, and it was mostly Dad who made her life hell, I grew up wanting to have a relationship where I would be able to avoid Dads behavior, in essence becoming the extreme opposite.
