Where does courage come from?  How is it possible that from time to time we seem to have the hugh amount of inspiration or impulse or anger to accomplish a great feat in our lives that under other circumstances we would never attempt?  We make our world so small. Courage comes from the desire to make our world expand!  Sometimes we muster courage when we have just plain  "had enough" of the same old thing!  We know that life can be so much fuller and meaningful and wonderful and interesting BUT...Why do we allow so many things to hold us back?  It takes courage sometimes to just get out of bed and put one foot in front of the other.
You were created to need freshness! You were created with curiosity and imagination and ability!
Restlessness comes from familiarity with our environment and our daily day to day living.  People are depressed because they think "this is all there is" to a life!  Have the courage to try something new today and shake up your world a little.  Take a different road or path, visit with someone you have been putting off, go see something new!  Take courage!
