Maybe I’m just not good enough at paying attention, but for me it seems like you have to actually run into problems over and over and figure out how to avoid the problems. Then you end up being able to mentally simulate what problems you will run into, and design is basically all about avoiding future problems of various kinds (and balancing tradeoffs about which future problems to avoid and how much effort to put into each, whether you can solve multiple with one design play, etc).
