Charitable work, helping others and helping in environmental causes sure helps.
designs, this is a key ingredient missing with JWs. They are told not to get involved in any of these things... that their time is better spent handing out magazines that usually don't get read and end up in the trash. My Father has been a baptized JW for over 24 years and has never had a study or brought anyone into the organization. That can't be very affirming (at least, from their viewpoint).
My parents became so 'disabled' in their thinking, that they stopped doing things that they used to do. The things that needed to be done to maintain the farm literally stopped being done because my Dad started pioneering.
It is when we put together a plan of action and then execute this plan, that we feel better in life. Actually helping someone has far more benefits than being rejected time and again at householders' doors because your beliefs are obviously nuts.
