8th grade is definitely early to be planning your career, but it certainly is never to early to get information.

I'd suggest you start with reading this thread and related resources on becoming a psychiatrist.

There is a lot of information in that thread. If you still have questions, feel free to post them in this forum.

its good that you have such high ambitions at such a young age but you must also realize that what you want to do with your life in 8th grade will almost definatley change by the time you enter undergrad school.
