Locomotive,
as several people have stated, 'Don't expect to become an expert over night'.
For a real world example, I started getting interested in computer security at around the same age (around the time I first saw the film 'hackers', I'll hide now...

). I've since spent six years studying computer science at college/university. And I mean computer
science, we learnt C, assembly, real-time scheduling, sockets, TCP/IP, etc.etc. not a course in HTML design. Following that I've had a security 'related' role for nearly 3 years.
I'm still yet to crack a real system, but I have spent several times incident handling for clients who have had issues or designing evironments to limit the risk/severity of such incidents.
Oh, and I still don't know jack and still have LOADS of stuff I want to learn (it's why I'm here after all).
Basically, keep at it and try not to take shortcuts, there aren't any.... (if I'm wrong can someone let me know

)
