Make senseI think Noh's point here is that nobody is stopping you from saying you want to do something ("I want to get stronger," "I want to eat meat"), but there will be obstacles in your way if you are not actually strong enough to actually train to BE strong or take the meat. Words are meaningless if you don't have the power to back them up.
Basically, it's a roundabout way of showing them that "talk is cheap."
