Being proficient and fluent in your language and tooling of choice is a superpower. What are the guarantees you get with different kinds of async behavior, how are null or maybe values handled and passed around, what are the default values of things and why. Not just knowing, but understanding questions like these will allow you to write code that is robust and has fewer unexpected side effects. In short, the trick is putting in the hours and hard work. Or, to quote MtG: "There is no shortcut to work done true and well."
