OK, suppose you get a publishing deal - perhaps not a big one, but your first one, and you feel great. You think "My work is done!" and start to relax...
You will now be faced with the first real challenge, that can make or break your writing career: Do you have a good, or at least original, haircut?
Many writers seem cursed with hair that makes children cry and run. "There, there, dear... did the hairy man frighten you? It's okay, it's not a werewolf, it's just a writer..."
It's not enough to have just a "decent" haircut. It has to give you distinct identity. Your hair will be your trademark... or damage your image.
You don't believe me? Look at this. And this. And... this.
