Mymar, first of all, I agree with bubby. Patience, and perseverance.
But, since you asked for advice, I will attempt to give some. Please note that I can only speak for my own perspective -- other people look for other things, but perhaps I can give you something to think about.
First, I would suggest that you create a signature, with a link to your Ons/Offs and your ideas. When people interact with you, having those things in one convenient, easy, place may go a long way toward increasing their interest.
Build those things up a little. Instead of saying, basically, that you like all kinds of stuff but don't like a few specific, grab their attention with what you do like, and maybe tell them a little about WHY. The more you give them, the more chance there is that something about what you say will 'click' with their likes, their ideas.
I took a look at your post history, and I believe I see the idea you were referring to as being 'too vague'. While you do have a plot, you've stripped all the meat off it, all the little flashy things that would make me see it and think 'what could I do with that plot?'
Nobody (well, at least, certainly not me) is asking you to create a world for an idea from the start. But sometimes when you reduce something down to its basic components, you're giving people a dry list of ingredients instead of a delicious-looking, yummy dish. It's like the old show 'Seinfeld', wherein the characters are pushing a sitcom that is the show itself. "It's a show about nothing."
Well, it is. But unless you already know the show, that statement doesn't give you a lot to work with.
Maybe write up a short blurb of your character, interacting with someone in his life after this 'strange event', make it a teaser. Describe your character a bit more -- not how he looks, but what makes him tick. You can do a lot to reach out and grab attention with a couple of paragraphs, but liven it up. Give people a teaser into your idea, something to hook their imagination.
When movies are advertised, they don't give you the whole plot, not by a long shot. No, what they do is lay out a couple of tiny moments that fire the imagination, that make you want to know the rest of the story. What we do here is, IMO, even more exciting -- we get to offer people a chance to MAKE that story, not just watch it.
Hang in there -- if writing/roleplaying is something that you want to do, then keep at it until you find the balance that works for you.
