Once more unto the breach?
My idea doesn't do anyone any good if it just sits in my head. If it is out there, living, breathing, even if it isn't what I envisioned, it is truly what it was meant to be -- an enjoyment for others.
Maybe my vision is crap. God knows Lucas may be the only person who thinks Lucas can write (notice how the more control he has over his films, the worse they turn out to be? Yeah, me niether.

). If it is crap, I'd rather have somebody else take it and enjoy it than have it sit in my brain and have nothing actually good done with it.
Yeah, sure, Greenwood is the poor sell-out? He's making millions of people happy, even if the criticism is scathing. Maybe the reason he gets criticised is that, like many other people, he's the only one who thinks his ideas are any good. Maybe the only reason people are enjoying the Realms today are the efforts of people willing to sell out. You don't need to be artsy to make people happy, y'know.
If I end up being that bitter that people aren't living out my dream, I hope someone smacks me. Until then, I will create what I think, which is a LOT of stuff.
You've said you've been rejected, right? Have you ever pondered the *why* of that? Think about what your work is missing, and inject that into it. You're the writer. You never have to write anything you're not going to be proud of. But take that creative energy, and make somebody other than yourself happy. Don't be too proud to show what you've been dreaming to others, even if it's not true, even if it is only a shadow.
