Here is how I found out that there is something wrong with me.
I was 7 or 8 when, during a parent-teacher conference, I was asked to leave the room. I went into the coat room and found I could still hear everything that was said. My teacher told my parents about an assignment in which students were asked how to divide 2 apples evenly among 3 people. The correct answer, it seems, was to cut each apple into thirds and give each person 2 pieces. Most of the class got it right, but three people gave wrong answers. One kid said to tell one of the three people to leave, then give the two remaining people each an apple. Another kid said to just go buy a third apple.
And then there was me, a quiet kid who kept mostly to myself. My teacher was worried - I had said to give each person a sharp knife and let them take as much as they wanted. When asked how my answer gave each person a fair share of the apple I said, in effect, that the three people would either be generous and take only a little, leaving more for the others, or they would all fight it out amongst them, killing at least one of them, and then split the apples.
My teacher then proceeded to ask my parents if I'd ever been caught mistreating pets or weaker children. I laugh now, but at the time I was hurt and outraged. It was a different teacher who recognized my unharnessed imagination and set me on the path of channeling it into storytelling, but I still spent many years after that thinking there was something wrong with me because I didn't see the world the same way as everyone else.
As writers, we don't see the world like everyone else. If we did, there would be nothing interesting about the stories we tell, and therefore little reason to tell them. It is our own, individual skew on reality that makes our stories unique and fun and ultimately readable. If anyone tries to tell you what's wrong with you, own it proudly. Because what's wrong with you and me as people is very right with us as writers.
