pessimist - a person who expects the worst
optimist - a person disposed to take a favorable view of things
these 2 are opposite ends of a magnet
Like Smiley, I have an odd view when it comes to this sort of thing. I'm a hopeful pessimist. I expect that everything's going to go horribly wrong deep down, but I always try to convince myself otherwise, and I hope for the best. Even though I tend to feel nothing can be done to help in dire situations, I'll still give it my best shot if there's no harm in trying. And if a hopeful pessimist can't actually exist, and this doesn't sound pessimistic enough for what I would class myself as, then I have no clue what I am.
