I take pride in my characters, so much that I recently came to realize a problem I had. I willed all of my main characters, or even significant characters, to be extraordinary. This is not, in itself, a bad thing; there are many successful, and entertaining stories where every character can be seen as phenominal in one way or another, but it is something that unecessarily limits one's options. I've been fiddling with a new plot, and I had just realized that it calls for the character to be a normal person (relatively, at the least). Now, to me, this wasn't so much difficult to do as much as it was rare. So, in short, take a step back and make sure you're not limiting yourself when it comes to character traits. I was.
