It's a video game so if you're going to learn that lesson from that one, then hopefully you don't play its companion game, Mini Metro, because otherwise you'll conclude that train-centric management is also futile.

But in a different way. In Motorways you actually run out of space to build infrastructure. In Metro you run out of "money" (as represented by incredibly limited resources). They are both games where you're guaranteed to lose (in pursuit of high score), but the gameplay-feel is very different.
