Are you an Optimist or a Pessimist?

I'm in between. When working on something, I certainly look forward to making it succeed but somehow make a little space for "what if it wont work out" kind of thing.. Sometimes when you expect things to work 100 percent, and it fails, it's very painful. By staying in the middle, it helps me cope up with whatever failures that may come my way. My guiding principle is, if it works, it's great, if not, try again.
