You don't want much, do?! Start college and you will find that usually the first two years make you take liberal arts courses which will help. Go to any library and look up the "Occupational Outlook Handbook." It has a huge amount of helpful information.
You don't tell me where you are in school. In undergraduate school you will need to major in psychology or sociology, then go to graduate school to major in what you want by that time.
I suspect you will get a lot of good out of the book,"Occupational Outlook Handbook" at you local public library.
