There’s a few things that usually need to come together in various ratios for success - hard work, efficiency, talent, and luck. A person can still be successful with any single trait, but it’s less likely. What’s more, with multiple traits, the additional advantage is multiplicative. Hard work and efficiency are the two that are most easily under our own immediate control, though talent can be developed over time. (Some might argue luck to be a thing that’s made, but I’m using luck as purely uncontrollable outside influences.)
