My father would make sure that I knew what it meant. Just to give you an example, I started bodybuilding with the age of 15, and my father would say, why are you lifting these dumbbells and barbells? Don't you think it would be better to just go out and chop some wood and shovel some coal for some poor people that don't have anyone? Therefore you would get muscles. But at the same time, you're doing something useful. You're doing something for somebody rather than just for yourself and looking in a mirror at yourself and stuff like that. So he would make sure that you knew what being useful meant.
