Every problem that needs to be overcome, every obstacle in the path, every idiotic decision I curse is something I did previously just to get things working. Then I run out of space. Or I need to pipe water in. Or a factory is outputting to the left when outputting to the right would be a better decision .... hmm ... do I move 200 componenets or just ... slap a train station in? Or 1,000 belts? ARGH! I've done it again!
