"Too much caution is bad for you.  By avoiding things you fear, you may let yourself in for unhappy consequences.  It is usually wiser to stand up to a scary-seeming experience and walk right into it, risking the bruises and hard knocks.  You are likely to find it is not as tough as you had thought.  Or you may find it plenty tough, but also discover you have what it takes to handle it."
-Norman Vincent Peale
