Children Psychologist...

I want to be a children psychologist, when i go to college Im going to major in psychology and become a children psychologist. I want to be go beyond a masters and go into a doctorate degree. I want to be a children psychologist to be able to help chilrden and teens overcome their problems. I want to be able to help them because i know that some children undergo serious situations and their parents do not know how to treat the situation and that is where the parents come to me so I could help their child. I also want to know how children are affected by the society and how they think.
