You are building a house and you need bricks for the walls, but the bricks supplied by the only manufacturer around are not fully square so you need to reshape them. To do this you need tools, but the tools are not completely done yet. The hammer is quite rough in shape so you need to ship it off to the factory between each swing, and the chisel is a placeholder made out of porcelain. To avoid breaking the porcelain you decide to just swing the hammer at the bricks carefully to chip off smaller pieces, but this takes an eternity and the bricks are fragile so they break in half after a few swings. You decide to see if the bricks can offset each others to complete a straight wall, but they have too uneven shapes that leaves gaps so the mortar is seeping through and gets hard to control. You try to set up wooden straightwalls on either side of the brickwall to help placement of bricks, but the brickwall catches fire from lightning in a sudden thunderstorm, the mortar gets soggy from the rain, and the wall slides into the mud.
The next day you try again with slightly improved tools and you end up with about 25% of the wall you began building the previous day. Unknowingly during the night the bricks you used are made redundant. When you get back to work the day after, you cannot find more compatible bricks so you have to start over again.
