Janiskan,
I think you need to quit thinking in terms of rejections being a bad thing. Every writer gets them. Heck, I've even gotten one. But the thing is, they can be constructive. If you get one, look to see what you might have missed in your work, something the editor may point out, or use the rejection itself as fuel to move forward.

The REAL trick is to experience life in ALL matters, in everything it has to offer...not dream about what COULD have been.

Submit your work. If it comes back, submit it again...and again...and again...
