Trolley problem. First mistake could be to do nothing at all!

There are people who are very productive who make very few mistakes.

Just like there people who can snatch defeat from the jaws of victory nearly every time.

Few is not none, besides that those people who are very productive and that make very few mistakes usually also were younger when they were still learning and likely learned a lot from those mistakes so now you see the end product.

That is true, but realize that those are the people that stay in their comfort zone and repeat the things they already know.
