Any advice?

Hey guys,
Sorry to bother you all, but i was just wondering if any of you had any advice on how to get into the field of directing?
Just to let you know I'm not just trying to get fame and glory and I know that posting this here isn't going to jump start my career, I'm not as naive as some of my fellow sixteen year olds. And I am looking into courses and things like that myself I just thought it would be great if someone could give me some pointers or maybe even tell me if any of the courses around are just a waste of time.
At school I have directed a production of "The Man from Mukinupin", I really enjoyed it and (not trying to be up myself) I was really good at it. I am really creative and I have the determination to do just about anything and so I was just writing to see if any of you knowledgeable people had any advice for me.
Cheers,
Nicole
