I tend to not have to handle things that are probably gonna end up being irrelevant, that aren't gonna have much to do with the film. I have probably a better understanding of really what does matter, when to pick my battles and when to kind of let them go.
Too much knowledge could be a bad thing. I was lead to the Szemerédi theorem by proving a result, about squares, that Euler had already proven, and I relied on an "obvious" fact, about arithmetical progressions, that was unproved at the time. But that lead me to try and prove that formerly unproved statement- about arithmetical progressions-and that ultimately lead to the Szemerédi Theorem.
