Picasso did not create 100,000 great pieces of art, I have seen several that were not that great in my opinion, the pieces I saw were rough, mean spirited.
We all know that some experiments that don't work, and so did Picasso, but he knew that the more times he created, the better the odds that he would create something interesting, and that because it was interesting, it might last. The man was a machine, and worked hard at his art constantly. It wasn't a job, it was his life.
How does it apply to you?
The more actions you do, the more times you create, that you get up and try, the better the odds of success and greatness. If you think one idea is all you need, you are wrong.
You need hundreds of ideas, and then you try them out with small bets or experiments, and then push hard on the concepts that work.
The real key is to have hundreds of ideas, and then actually execute part of it in a small way to see if it works.
Over and over.
An idea withoout an action is worth nothing.
Picasso didn't know which pieces would be lasting pieces of art, he just knew what interested him, and he tried what he thought about, learned from those around him, and then pushed hard on those ideas that worked the best.
