Daring to excel means having the guts to speak up or take action, when needed... especially when others do not have the nerve.  It can be simple, easy, and harmless.  Or, it can be complex, difficult, and dangerous.  It means being aware of the efforts involved, the obstacles you may face, and the consequences of failure, and still being willing to proceed.  This very site is a small, somewhat complex, fairly easy (for me), and harmless (I hope!) example.  Enjoy!
