> may not necessarily see the value in gathering random notable ideas somewhere until you put in the effort of documenting them and then see the network effect in action

or it could be that correlation doesnt imply causation.

People who have lots of ideas might just generally be better at ideation, have high intelligence, and perhaps also good at evaluating their ideas quickly. Their success is not _due_ to their jotting down of ideas, but that there is a confounding factor that influence both.

People who would copy the actions of successful people may just be cargo culting.
