You wish to raise your
spirits?  Move your attention away from
the self and focus on those around you. 
Choose one who appears in need of a smile and give them one.  This simplest of actions—not the smile, but
the shift of focus from self to Self—will move you from the trap with which ego
so often ensnares you. 

All humans face
challenges.  In this you are not
alone.  By helping another to lighten
their load you lighten your own.  It is that
simple.  Yes, of course you know this,
but do you see how ego keeps you trapped: 
In focusing on your own concerns you forget the simplest of gifts.  In giving to others you give to yourself.
