The most powerful thing is a negative attitude. It's pretty easy to ensure that everybody around you is miserable and that nearly all of your outcomes are terrible. However, the opposite is unfortunately not possible: you can't make everything great just by being positive. Therefore, it is best to be pragmatically positive. Recognize that positivity gives you the best chance to succeed... while recognizing its limitations. When you cross that line, that's when it becomes "delusion and denial."
