What kind of studies will you be undertaking. I would reccommend going to a school and just delving into the textbooks there so you have other people in your classes to talk about it with. I'm studying psychology as well and got interested in it from having had to go to counselors myself. I'm in my senior year of undergrad, and believe me, there is A LOT to the field. If you get involved in a school, take as many classes as you want and the ones you are especially interested. Even the ones I didn't want to take at first like Behavior Disorders really opened my eyes to issues that people were struggling with. Positive Psychology is a great subject to if you ever get a chance, I thinnk someone on here did recommend Seligman, he's great. Follow your interests.

Some other great things to do might be to just read novels or true stories about people with various issues going on in their life. We read the novel "I Know This Much is True" by Wally Lamb in my Behavior Disorders class, and it weaves in different issues, with their actual life, and doesn't tell you the name of the disorder or anything, so you see how psychological issues affect real peoples lives, not just something from the textbook.

Good Luck!
