Sure, but there's also tons of people who worked full-time for years without anything to show for it, I'm not sure that short-term intense focus is any less subject to survivorship bias than long-term regular focus. I do believe that at least one of them is necessary but not sufficient for most types of "success".

At the end of the day, I think outliers (across all axes) is what makes for interesting articles that get upvoted, and so if you squint hard enough probably every article is subject to some kind of survivorship bias.
