Joy comes from loving God and neighbor. Pleasure is quick and violent, like a flash of lightning. Joy is steady and abiding, like a fixed star. Pleasure depends on external circumstances, such as money, food, travel, etc. Joy is independent of them, for it comes from a good conscience and love of God.
Sin is a disproportionate seriousness.
When you are getting kicked from the rear it means you are in front. They can be overcome. Invented ones are like a maze. What you love is as unique to you as your fingerprints. You need to know that because nothing will make you really happy but doing what you love.
