In my opinion, contrary to what some elites say about luck not existing, luck absolutely does exist. And contrary to popular belief, "luck" is not an actor, but a recipient. That is, luck, in its literal English sense, is equivalent to a set of probabilities and variables. Naturally, controlling more of these probabilities and variables increases the chance of your desired outcome. Understanding more elements and variables in this cycle raises the likelihood, or the "luck", of achieving the situation you want. It's really that simple.
