You know what? This is indeed where courage, tenacity, and risk-taking make a difference.

But what makes the difference in whether or not we hear about it is pure luck and survivor bias.

If their luck was just right that with all that push in the right time the deal came through or the product sold, then we hear about what a great success it was, and how important was their grit.

And many smart determined people with all the courage, tenacity, and risk-taking in the world have also taken the big risk, but dice did not roll their way, or the hill was just so steep it didn't work, so we hear nothing of them. And their number likely vastly exceeds the few for whom it did work.
