Courage is the power to face your difficulties.  It comes from the reserves of your mind that are more powerful than your outside circumstances.  When you recognize that you're bigger than your problems, you'll gain the courage necessary to overcome anything.
 
Your obstacles will look large or small to you according to whether you are large or small.
 
Courage is the capacity to confront what can be imagined.  It gives you the ability to rise above your present reality.
 
Reality is something you can rise above.
