From Stephen Covey ("First Things First"):
The 4 areas of human need are: To Live (Physical), To Love (Emotional), To Learn (Mental), and To Leave a Legacy (Spiritual). To ignore one, some, or all of these areas means you will not feel whole nor happy. Your life will be 'missing something'.
JWs focus mostly on 'spiritual' to the detriment and sometimes, exclusion, of the other needs, especially when they 'dedicate their life to Jehovah'. I tried to explain this to my father that a harmony in life is needed and by pioneering, his life was not in harmony. Everyone's 'purpose' in life is unique to that person. The WTS definition of servitude to Jehovah is not balanced with the 4 human needs, nor is it unique to each person. If every single person on the face of this planet went door-to-door, who would do the doctoring, teaching, farming, road repairs, etc., etc., etc.? (Let alone, finding anyone at home! )
Trooper, a Canadian Rock band, had a song out back in my day called 'Raise A Little Hell' and the words from their song are very appropriate here:
"If you don't like what you got why don't you change it? If your world is all screwed up, re-arrange it."
We are the architects of our lives. We design it and make it what it is. The WTS (or any other religion) has no business doing this for us!
