Not too much heaven, please

Many conceptions of bliss or heaven depict a place and time of zero problems and negatives.  But I wonder if humans don’t need and depend on a string of difficulties and problems that assist us in noticing and enjoying times when things are just right.  I think we are built and evolved to be in this world of pestilence and pests, disease, failure and pain, disappointments.  As with much of our lives, we may profit most from the right balance of negatives and glorious, wonderful times.
