If your house is in full flames engulfed by the fire, then a little bucket of water isn`t going to be enough.
I "talked" to a psychologist student in a forum, it was so good to meet someone in that branch who got deep psychology. My impression is that a lot of psychologist students are people who want to study about the mind, and people who want a higher education so they can get more money. Also the idea of understanding behaviour is also something that interests a lot of younger people.
Also i think that some of the people who chose that study are people who maybe really wanted to be doctors but didn`t like the sight of blood?
Some people who study psychology have been thru bad things themselves and therefore uses the study not only to help others but also themselves.
I don`t see anything bad in studying psychology but i see a lot of contrasts between the professionals.
Some do everything after the book and some are professionals.
