My experience in life (which including being on teams that did the “impossible” routinely) is that motivation is the most important factor needed in success.
I like to use the analogy of my old hound dog.
If you met him you would think the poor guy was on his last legs—until he goes straight into warp speed to chase a rabbit.

I’ve got a friend with a dog like that. Turns those old fella’s into pups in a split second!
