I'm thinking of the many JWs who say: "I'd love to learn violin, I'll do it in the new system". Or are interested in politics or animal welfare or whatever, but put it aside because the "end" is coming soon.
Having children, education, a love life at all if you are gay, travelling the world ("in the new system we'll travel the world by yacht" heard that one?), pursue an art or craft. Often pushed aside for "the sake of the kingdom".
JW ideology inhibits a good life now. Some other religions are actually capable of promoting a good life not hindering it.
On some level JWs are aware that being a JW is a recipe for a miserable life here and now. They accept it because they think there is better to come.
