C.S Lewis. If you have to ride on someone else's motivation until your own can carry you forward; "Do what you must until your past is so far behind you, the future is ALL you can see". "It's so much brighter then you've ever been told". This I promise!
Focus on the good - "Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things." Philippians NIV
