Not good enough for what?
If you write a thousand pages and a thousand people read them but only one person's life is turned around by one line and you never know about it... well, I call that a win.
For me (and others)writing here is not about having the best thing ever written, it's about learning, teaching and growing. I both read and write here but thinking about and discussing ideas is what grows a mind. I think you will be surprised how many people identify with what you feel, no matter your writing ability.
Publish something you are interested in, and LET ME KNOW, I'd be happy to read it.
Just a small warning though, lots of really good stuff goes unread because nobody knows about it yet. There are many books to help you with that, but it never hurts to be voting and commenting on things you like.
Last thing, the authors reads and votes are counted too, so vote whenever you read your own stuff. It sounds dishonest at first, but if there are no votes, it won't get in front of many people so they can decide for themselves. How many people want to read something they think the author didn't like?
Sorry to be so long winded...
