Trying to get published waaaaaaaaay too early. I wrote dozens of things when I was a teen, but wrote them all with the assumption that I needed to grow up and write proper stories that weren't copied off other author's books before I would get published. I considered my homages to Tamora Pierce, Susan Cooper, Terry Pratchett, Ursula Le Guin, Piers Anthony and Alan Garner 'practice pieces'. I accepted they weren't good enough to be real books.
I don't know if it's the internet, or Christopher Paolini, or what, but it seems young Zolah's attitude on that point is not shared by the majority of starting-out writers these days.
When/if they can't GET published, they get really, really angry with anyone who can, and all publishers, editors and agents, and then go and sign a contract with Publish America. Or, if these young writers do have talent and they manage to cobble together something fairly coherant, and THEN happen to approach an editor or agent who hasn't read whatever story the young author is ripping off, they end up having a bunch of derivative drivel published, and they can feel ashamed of it for the rest of their lives. Not win-win.
These guys should be honest with themselves, and accept that if everything in their story from character to theme was 'inspired' by another story (or stories) that they love, then it's not a real book, it's an homage and it needs to go in the drawer, not in an envelope to HarperCollins.
