Most of us think of the business leaders behind the modern
internet as clean-cut, scientifically minded overachievers,
such as Amazon.com’s Jeff Bezos, Facebook’s
Mark Zuckerberg, and Google’s Larry Page and Sergey Brin.
Given that most of them were there for exactly long enough to decide it wasn't worth staying and left, how exactly does that matter? Being clean cut isn't just about pedigree.
Page and Brin were PhD students, so very much not just there long enough to decide it's not worth it, as they had at least graduated from a bachelor's, and had likely been there for more than a year after. Bezos graduated from his bachelor's degree.
