So, why is it that we have nothing interesting to say about ourselves or our profession? After musing for a few days, I've come to the conclusion that I haven't really thought about my image and what I'm supposed to convey. A writer's a bit like an actor; we need to prepare ourselves in order to appear mysterious yet approachable, insightful yet modest, but in no way mundane.
Don't pretend to be someone you're not because people will see right through it. Just research your personality like a good PR manager would research a brand and focus on the interesting traits that help you stand out from the crowd. If you're funny, then by all means go on and build your image around this part of your character and your audience will come to acknowledge you for your humour. If you're super-clever and articulate, then that's what you should focus on. It may not make what you have to say more interesting, but people will start to see the personality behind it, and in our competitive world seeing a human side behind a brand or product is what can make a difference whether your audience starts to like you and buys your books. Decide on an image and keep it consistent as you build it, and your audience will start to perceive you as someone they 'know'. That's one of the tricks to branding: connect to your audience in a way that truly reflects who you are. Put your character behind your words and whatever you say will suddenly appear to have more depth even if it's all been said before.
