And honestly, a lot of ideas were terrible until they were executed. It was only through the process of exploration & execution that a practical use or market emerged & evolved from the original spark.
This is not such a great approach to take if you have limited resources. Sure you might get lucky and find a great idea (ala AirBnB) even though your first idea is not great, but it is not the optimal way to proceed. I would much rather start with a good idea that I try to make better, than a terrible idea I have to figure out how to pivot into a good idea.
