Lets say you shovel some dirt, you’ve got a lot of control over where you get it from and where you put it..

Now get in your big digger’s cabin and try to have the same precision. At the level of a shovel-user, you are unpredictable even if you’re skilled. Some of your work might be out a decent fraction of the width of a shovel. That’d never happen if you did it the precise way!

But you have a ton more leverage. And that’s the game-changer.
