Nothing can be done without effort. But not all effort is the same. It depends on leverage: if you push a door on the edge, it opens a lot easier than the middle or hinge-side.
So the challenge is to know where to apply your leverage. Getting the muscle is simple, knowing where to apply it is complex.
It’s an undefined game: the task is to give meaning where before there was only empty space.
