Arrogance

If you want to accelerate your rate of personal growth, work on becoming as honest as possible, both with yourself and others. The more honest you become, the more accurate will be your model of reality. And this will dramatically improve the success rate of your decisions and actions. Overconfidence and underconfidence are equally problematic, so strive for accuracy instead.

Certainly there is a time and place for emotions. (Appropriate emotions of course.) But my experience is that any time my emotions, or my beliefs get a hold of the steering wheel things veer badly. I do much better when I use my brain to think things through, sort wheat from the chaff, and make plans. I’m not sure where I’m going, but I sure know where I came from.
