I'm sure you have all hear the old phrase "I'm not being pessimistic, I'm being realistic." But where is this imaginary line truly drawn? When does looking at a situation take a pessimistic turn rather than a realist turn? Personally, I believe that pessimism starts when you start applying Murphy's Law to the situation. Murphy's Law of course states that anything that can go wrong will. Sure, realistically odds are that not everything is going to go right. One or two things are bound to be off in any situation, but when you start calculating for even the most unlikely mistakes than you are taking a pessimistic turn. This is my thought. How about the rest of you guys. When do think the line between realistic and pessimistic has been crossed?
