There are two kinds of fear: good fear and bad fear.
Good fear is when the hairs stand up on the back of your neck. The kind of fear that tells you to cross the street for “some strange reason.” The kind of fear that gives you superhuman strength in dealing with sudden danger. The kind of fear that immediately threatens your physical survival and that prepares you for dealing in the short term.
That’s the good kind. It’s rooted in our animal instinct of pure and absolute protection of ourself and our clan. Good fear that we only want to experience a few times in life if possible.
Then there’s bad fear. The fear that creates the same kind of physical sensation you get from good fear: increased heart rate. Blood flow to the extremities. Rapid short breath. Bad fear is rooted in all the “What if blahblahblah happens?” What if? What if? What if? Bad fear keeps us on the treadmill of mediocrity. Bad fear keeps blood out of the brain, where we need it the most in order to make effective decisions.
