...as Dak said, Accalia, you're definitely in the right place to maybe kick up a nugget of inspiration or two. Hang around and browse, jump in a game or two... heck, start up a game or two... and before too awful long, I'm sure, you'll find that you've got more than a pocketful of sparkly nuggets of inspiration and imagination...
As to the embarrassment/nervousness/confidence thing; don't let it get to you and don't ever feel like you're being judged by anyone hereabouts. Like you said, yourself, you're young and "new" and looking for a firm path to put your feet on, yeah? Everyone starts somewhere, little miss and I'm pretty sure that everyone, in their beginnings, had similar thoughts and concerns ("Geez! That sucks!" or "Crap! Why can't I get this to come out right? I'm such a loser!") The thing is, whether we started years and years ago or just yesterday, I'm sure we can all look back at those first steps we took towards writing, drawing, storytelling, or whatever and say "Wow! I've come a loooooong way since then, haven't I? And, you know, even though I thought that story (picture, whatever) kind of sucked, then, I can look at it now and see how it grew from that rather lackluster little seed into this WORLD SHAKING EPIC TRIUMPH that I've got going, now!"
Point being - Each footstep is a beginning and an end; there is no path, only the journeying.
Keep on keeping on, little lady, and, if you need help or inspiration, just give a shout... one of our fabulous Innmates will always come running to offer insight and encouragement... I can practically guarantee it.
P.S. Moved this one to the general forum as it seems to fit better there.
