I've often thought that those happiest as JWs were the ones who didn't really believe in it. I remember members of my old congregations who looked like the perfect JWs, they also looked very happy...kind of a contradiction, unless they were just playing at being JWs for their families. I've decided that at least one elder and his wife had their JW facade down to a science. They would attend most meetings, they'd go out in service at least once a week...or they'd make sure everybody knew that they had a weekly Bible study so that no one would questions whether they were getting out there and talking up the WTS. They'd take vacations, but would talk loudly about what Sunday meetings they were planning to attend during their visit to Florida or California. They'd buy or build new houses, but would talk about how they didn't get the biggest or most luxurious place possible.
It was interesting. While they did have to spend a lot of time making sure everybody believed they were devout JWs, they didn't have to actually DO a lot...just had to make sure everybody thought they were.
I was a fool and thought I had to practice what I preached, no matter how unhappy it made me. Of course, once I realized that I didn't believe in it any more, there was no reason for me to stay as I had no family in.
