In what way is luck important? One part of me says someone that identifies an urgent market need and executes on it doesn't need too much luck. On the other hand, maybe luck is important in terms of your network: meeting the right person at the right time. (This leads to "luck surface area" arguments.)
Warren Buffett, Bill Gates, Elon Musk, Jeff Bezos, Charlie Munger, Ray Dalio, Mark Cubam, Ophray, Richard Branson, Steve Jobs, Jack Ma, Howard Schultz, Sheryl Sandberg. And many more mentioned Luck played a big role in their success.
Please use google.com search for the name of the person + "interview" + "luck" and you will find the first results to be the relevant ones.
Yes, I have seen many of the interviews from these extreme outliers. But I am curious to hear regular people's experiences with luck, and whether they have succeeded without much of it, even if they didn't become billionaires.
