It depends on what type of people who needs us. If a stranger needs you to play a song for their own satisfaction, do you need to do it for that stranger? Of course not, you don't need that stranger. If someone like your parents needs you to buy ingredients for your food, do you need to do it for your parents? Of course not, they have their own feet. But what if they we're extremely exhausted after work? You would eventually need to get it on your own. To simply put, the answer is yes and no.
