It's been said the true definition of insanity is doing the same thing over and over again while expecting a different result each time. In a sense we writers could be considered an insane lot. We market our wares the same way over and over again, in the hope that one day someone will say, "Hey, I'm gonna buy that!" after seeing the same ad a hundred times.
Is what you're doing today getting you closer to where you want to be tomorrow?
