In martial arts, in order to break an object you need to focus on a point beyond it.
This is pure physics.
For every action there is reaction and resistance. When applying your power and speed through and beyond a target, their vectors will be pulled back towards you. So eventually you end up breaking the object.
The same principle applies to human life in general.
If you want some result, you need to work a lot. And if you want a stunning result, you must work off your ass for it.
We must aim high in order to achieve something. Simply because there will be resistance on the way slowing us down.
And in order to achieve most we need to aim as high as possible.
