Positive people are dangerous. Because they assume everything is going to be fine, they fail to plan for things to go wrong, and then after you're stuck cleaning up the mess they caused, they sweep it all under the rug and act like everything went smoothly - so not only do you get no recognition for your heroic efforts to fix everything, but they're fully confident in their ability to handle the next situation just as well as the last.
But nobody wants to listen to the pessimists, because they're so negative.
