Gratitude. 
Can you apply it to everything in your life … the so-called bad things
as well as the clearly good?  All of life
is about the experience and the learning that occurs from rolling about in
those experiences, fully covering yourselves in the variety of them.  Can you be grateful for the challenge?  Not until you see and apply the lessons.  Are you feeling bitter about a past
lesson?  Then you have not looked for the
lesson or it has not yet revealed itself. 
Perhaps the lesson in your challenge was not yours to learn, but someone
else’s.  Souls do that, you know …
volunteer to undergo a challenge so that others will benefit.  Humans are often not so generous, but souls
understand the oneness.  Be
grateful.  Gratitude opens the heart, and
perhaps with the heart unleashed you will see the blessings that your life
allows.
