It says a lot about her that she answered so gracefully about her ex though. That garners a great amount of respect from me. So many exes are just bitter and eager to stick the knife in. It's refreshing to hear someone say positive things about their ex.

The opinion is as generic as that of a random person. There's nothing in the answer which provides an actual insight into the making of a billionaire.

Maybe there are no insights. Maybe it is all a sum of the generic things she spoke of, and pure luck of having successful consecutive ventures.

But to put it simply, it's not that great of a Quora answer.

It probably wouldn't have garnered as much attention, however, this appears to be a common sentiment of those largely considered rich and/or successful. It doesn't make the advice less valuable.
