Lack of utility of life draining emotions

“You must absolutely convince yourself of the lack of utility of life draining emotions. You must see your unnecessary worrying as depriving you of the flowing effectiveness and joyousness that you should have in your life. As long as you think these negative emotions have any function whatsoever, you will retard your growth into higher consciousness.”
