However, truth is a relative and depends on time, space, culture, tradition.... So it is hard to determine what is the truth when it comes to human psyche.

If I can speak to myself I come from country where being cold is the standart. I often wonder that maybe I would do much better in Italy, because it would be normal to scream, squeel and cry and I would not struggle as much. Of course, that is a speculation... but I definitelly had problems with perfectionism and emotions. I feel I did impose some of my mental quirks on myself.
