Pursuing happiness is a meaningless goal because it can never be achieved.
Goals that help us fulfill our calling can always be achieved. They never distract us from our purpose. Pursuing happiness is a lifelong pursuit that can never be satisfied, and completely throws us off the path of doing what we were made to do.
When we pursue happiness, we never actually experience what we set out to gain. This is because pursuing something only brings reward at the end, and if we can’t reach the end then we will never experience our desire.
