It has been said, that it's not the experience of pain that brings hopelessness, i'ts the inability of pleasure to bring satisfaction. What do I do when what is supposed to make me happy no longer does? How then will I find the will to live? What purpose will I serve? My desire for pleasure is like a fire. It is never full, I keep feeding it and uses that up and wants more. No matter how much I give it, it is never satisfied. Soon the glowing embers of want beckon for more fuel. At this point, there must be a resetting of my pleasure threshold. In this lies at least one purpose to feeling discomfort and pain.
Food never tastes so good as when I eat after going hungry for awhile. There is a proverb that states, “ A full soul hates even a honeycomb, but to the hungry, even a bitter thing is sweet”. If I always do only what feels good, I soon burn out trying to stoke the boundless appetites of my pleasure fire. When I do myself a favor and deny my appetites, I find that when I "eat" again it's all the more satisfying.
