Self-centeredness is the greatest enemy of spiritual life because by putting yourself in the center you drive God out. Once you and I are alienated from him to whom we owe our existence we can never be truly alive, no matter what this world gives us. Put self in the place of God, and you may get the best education but you won’t be fully alive. You may become a millionaire, but money doesn’t buy happiness. You can be successful and empty at the same time.
