In fact, there is an unbreakable rule in the Vinaya that it should not demand ordinary people to do anything that they are incapable of doing. The Buddha knew very well our limits and thus would not ask for something impossible of us. He did not say that everyone must lead a life of hardship but that we should control our desires and spend time and energy for something more meaningful in life. Otherwise, we can never be really happy or accomplish anything worthwhile. Do consider this point carefully.
