One of my favorite world-design tire-kicks: making LOTS of characters, as if I were a player getting ready for a #Hammondal campaign. If I bump my head on questions and can't _finish_ a character to my satisfaction, those questions get added to the design workload. If a character feels "meh," I tweak the world design to give them more to play with.
Some of the characters might then become parts of the worldbook. Some may become pregens for adventures later on.
