It's like building a deck except even the screw hasn't been invented yet. And you think: I'll just create a device that attaches the wood like a big paperclip but then realize after you make it that it's not strong enough and won't scale so you create a nail. But then you realize you may need to reuse the wood so you finally create a screw.that can be removed.
