A Psychologist is someone who helps people figure out their problems, it could be anything. Bed wetting, they've had some bad experiences in life. Anything like that. There are also different types of a Psychologist, there is a Social Psychologist, Child Psychologist, Sport Psychologist etc.
I have no idea but I would love to do this when I get older. Right now I'm only a freshman but this is a career ! Have thought about a lot in my 14 years of being alive.
