Most of the folk here are, or were, I T professionals in the strict sense of the word. I believe most are from a security or systems background.
Me, I'm the black sheep of the site as I have been in engineering all my life. However, computing subjects interested me enough to base half my degree course on hardware, programming and databases. So I am not a professional in that sense, though I try to be as professional as possible when I'm here.
Sorry - that doesn't even begin to answer your question, but I'm sure some of the others will be along shortly to advise you.
Whatever direction you choose, enjoy it or else switch to something you do enjoy!
Good luck ;D
