Yeah....I'm not "joyful" because I don't know how to manage my time.
It has nothing whatsoever to do with mind-numbing meetings, pointless knocking on empty houses, Nazi-SS-guard-minded elders, lack of mental stimulation from reading 5th-grade level "literature", backstabbing congregational politics, unjust judicial cases, and endlessly repetitive "obey us or Jehovah will melt your eyeballs" messages.
