How do you define success?
This is such an subjective topic. I would ordinarily refer to “success” in terms of wealth and prestige especially the way our world works now. But I believe that we are spiritual beings at our core, so success indicates that you have a relationship with God. Once that fundamental aspect is addressed then all the other stuff can be taken care of.
