I am pessimistic, I think that's the best way to be, because if you're always expecting the best - the best doesn't always happen. Nine times out of 10 it doesn't. I'm surprised when things go smoothly. I don't know what's wrong with being pessimistic - unless you are such a pessimist that you don't do anything.
