Life is about learning our lessons, and everything else is just sandcastles in a rising tide.
What is a life lesson? You have learned a life lesson once you have been convinced, 100%, that happiness is not found in “x”, nor “y”, nor “z” because you have thoroughly checked. And once you have learned many lessons it dawns on you that perhaps happiness is not found anywhere “a” through “z”.
So maybe happiness is not a cup to fill, but a beacon to follow?
If the desire for happiness is not a goal to fulfill, it must be a homeing beacon, a calling home. What I call my desire for happiness IS actually my love and desire for God. I really want to be happy! I must love God VERY much.
