Have you found your own meaningful ways to stay in touch with humanity?
I have. I also understand the feeling of accomplishment, the (somewhat) sense of camaraderie or team work that comes form collectively working towards the same tasks, etc.
I teach, most of my entire work life have included teaching or training. I got involved in HIV/AIDS prevention education (talk about trying to convince uninformed people!) and ended up with an entire resume in that area of work. The good thing about the work that I did when teaching the basics on HIV infection prevention was that I ended up specializing in talking to people in churches and what they call "people of faith". As a JW I did acquired a skill that allowed me to reach out to pastors, ministers in a way that spoke to them, and therefore, being able to talk to people in their congregations about things that you don't normally talk about in a church. I was very successful.
Then I have done a lot of volunteer work around causes and social issues I believe in. That has proven to be way more fulfilling than going house to house telling people that their believes and behavior are wrong and they will get killed for it.
@ Pete Zahut:
The best thing about going in "service" was when it was over. Nothing
was accomplished other than to rid oneself of the guilt and obligation
placed on you by others. You got to feel somewhat virtuous about
yourself and got a sense of accomplishment buy doing little more than
driving around and knocking on a few doors at empty houses. This
sensation is what other JW's often mistook as "Joy".
I felt like that a lot, actually for most of my life as a JW. However there were things that I did enjoy and got very good at. I was a very darn good preacher. I used to specialize in talking to very stubborn, nasty people, some of which my fellow JWs would shy away from. I loved that challenge. Today I rather use my skills in something that actually matters, but I enjoyed it when I was doing that back when I didn't know better.
