Disappointments.  They go with the territory.  The human landscape is fraught with its ups and downs.  That is the point.  If all were steady-state, a level playing field, where would be the growth?  If you walk all the time, a little running strengthens the heart.  If everything is pleasant and easy, why question anything?  You learn from the challenges.  Not all situations turn out the way you would like, and when they do not, you experience disappointment.  This is not wrong or bad, but a learning opportunity.  There is wisdom lying in wait in the moments of sadness, disappointment, and even despair.  Continue mining those moments until you find the lessons, and may they be punctuated with moments of joy and knowing … knowing that there is always another aspect of you that IS steady-state.  Peace.
