I'm competitive. I want that gig. I want it and I want to rock it. When I don't get it, I always go back to see who did and if they are doing as well as I thought I would do in the position.
I used to jealously guard my leads. Mine. Mine. Mine! Then I began to open up to other writers. Contact them. Congratulate them. And you know what? I got more out of the relationships I fostered with other writers than when I shut myself away.
One of my most cherish relationships is with a writer I met after she got an editing gig I wanted. When the publisher wrote me to say the position was taken and advised me to contact the new editor because they are looking for writers I was sullen. "She stole my gig!"
Eventually I got over myself, contacted the new editor and found a new mentor and friend. She rightly deserved the gig. Sure I got work with the publication, but more importantly I got a friend in this biz with more experience and crazy enough to take me under her wing. She invited me to her writer's group and there I met three other fabulous women. I have been more successful knowing them.
Sure we're competing for the same gigs, but there are millions of gigs. Isn't it better to have a network of fellows than a network of perceived adversaries? You never know where good friends, fortune and contacts reside.
