Let’s assume that the answer is yes. You believe that hard work contributes to a life worth living for everyone. So, are you hard worker? If you are not a hard worker and you say you believe in hard work because it will contribute to a life worth living, then do you really believe in hard work? If you say you believe it but your life doesn’t show it, then, should I say that you don’t believe in hard work? Perhaps you say that you believe in hard work to be in agreement with those people who do work hard and believe in their work. Fair enough. Who wants to have constantly defend this view against society? That’s a lot of work!
Perhaps this is how belief often works. It’s less work to have to have people secretly disbelieve you than it is to have to try and defend your beliefs.
