Chance
While creative talent and hard work play an obvious role, chance and randomness also influence problem solving and creative discovery. Countless inventions and discoveries are accidental. The difference between what happens to us, and what happens to those chance inventors, is that they notice things, stop, take a step back, and reflect on what they have just witnessed, ask why and how, and use their curiosity to wonder what else.
While we brush it off, grab our coffee and run to continue what we planned to do.
