What Does Discipline Mean To You?

I've seen many mothers look for martial arts classes for their children to teach them "Discipline". So often they send them to a TKD school with a multitude of belts, lots of fun and games and admittedly not a lot of martial arts.



Discipline to me is going to a class when you really don't feel like it, or cutting weight. Standing in line and taking orders is easy. I don't understand where discipline comes in to it? Is it like a seed that leads to aforementioned discipline?
