Zuck executed the shit out of Facebook. In comparison to what? For all we know, there were dozens, maybe hundreds of other similar sites being built at the same time. Without being able to compare them, we really can't say how well he executed Facebook. Having used both Friendster and MySpace, I'd say he did better than either of them. But by the time Facebook was big enough to be mentioned in the same breath as those two, success to some large degree was already assured. Instead, I prefer to ascribe luck to things that the individual actually had no control over, such as winning the lottery. This is precisely the point: there may very well have been key moments in Facebook's history, over which Zuckerberg had not control whatsoever, yet which ultimately determined the company's fate. We know the economy is a nonlinear dynamical system, and in such systems small perturbations in the input can lead to large changes in the output. There's no reason to suppose that similar effects don't play a role in the life cycle of individuals or businesses.
