Not to brag (is it even possible to brag through an anonymous throwaway account?), but throughout my schooling I skipped or skimmed most readings and avoided doing the homework, or copied it off my more diligent classmates. But I still got perfect grades in high school and graduate school, outperforming classmates who worked much harder. In undergrad, I had mediocre grades only because I just didn't do the homework and often turned in term projects many days late, but based on test performances, would have also had near perfect grades. I have a bad work ethic which holds me back in other ways, but I'm still near the top of my field for my age bracket. If I hear something once, I understand it and remember it for life. I don't mean memorizing lists; I mean learning how something works and why and how to apply that knowledge.
