Both are simply beliefs, and I believe neither of the them. I don't ascribe evil or good to reality.
That being said, I don't dwell on best possible outcomes, but I like to be positive for the sake of people around me - while still maintaining my pragmatism.
optimism is basically a concept of trying to look upon things from the best possible perspective and looking at the plus, rather than the minus side. Pessimism is the contrary, you look upon the negative parts first.
An example:
Let's say you are trying to restructure a company. 53% of your staff is for the decision, 47% is against it.
An optimist would say that it is a good result as more than half the people are supporting your choice, while a pessimist would say that almost half of the people are against it and that you should improve it / rethink it.
A realist would say, that 53% is a good start, but that there is room for improvement.
Of course that is an extreme example, but that is how it works out, it has nothing to do with good or evil as mentioned :)
As to reply to the other posts:
Yes, I do think the words optimism and pessimism are used way too much in the modern language, because they are trying to emphasize that there is a "large" positive or negative notion (which is often wrong).
Also, at least that is my opinion, even a realist can tend to be either optimistically or pessimistically, though not to an extreme a "pure" optimist or pessimist would.
