Can't say anything about entrepreneurship but when I learned to ski between ages 28 and 32, then yes it helps a lot. I could categorise the type of painful falls I'd make and how serious they were. I had whole failure models built on not breaking but falling into the snow.

It took 5 years to ski, especially the first 3 years were a painful process.

(on avg. 1 week per year)

Not sure how much this resembles entrepreneurship.
