Thinking a lot about this phrase from Stephen King’s “On Writing” a lot today. He said it specifically about writing, but I have found that it applies to idea generation in-general.
There is no Idea Dump, no Story Central, no Island of the Buried Bestsellers; good story ideas seem to come quite literally from nowhere, sailing at you right out of the empty sky: two previously unrelated ideas come together and make something new under the sun.
