What good is psychology in the world.

The world is made up of many people with unique experiences,thoughts,and life goals.Sometimes events,thoughts,trauma get in the way of your life and maybe a little help would not be so bad.I believe psychology is very important,because it helps people realize what the person or what you are all about.Some people need it more than others.Personally I like psychologist and If it wasn't for them I probably not be here today.There just people that help you clarify your thoughts.Psychology is a very vast field ,many people don't even realize there is different types of psychologist.
