Coates’s attitude toward writing neatly encapsulates Duckworth’s primary thesis about grit: even when success looks like the product of natural genius, it generally depends on a long, arduous process of practice, improvement, and self-discovery. The key to navigating this process successfully is learning to set high expectations, failing to meet them “over and over and over again,” and pushing on anyway. All “geniuses” start out as ordinary people with ordinary problems, with one key difference: they’re gritty.
