Usually when someone says to someone else, "Relax," they're asking the other person to be calm and rational. Well, "believing" generally entails the opposite: be irrational and let your emotions guide you.

As much as I enjoy and need my emotions, I also work hard at holding them accountable. It's the best game in town, but there's no blind faith involved. Quite the opposite, and the end result is me relaxing in the knowledge that my emotions and my rationality are happily coexisting. Ouch!
