Even though Van Gogh was in great agony, he painted beauty.
 
I think that is a good lesson/example for us.   You and I have our own agony/struggles.  And while I know how hard it is to extend yourself to some higher purpose just to be less grouch,  to show kindness in the face of what is not being,  to give something other than ugliness.  We are better than then agony that torments us.  What ever you agony, give the world your beauty.  
What is your beauty that you can share?
