“Practice makes perfect”, as the English idiom says, we know the good sense of working hard and repeating our hard work to achieve our success. And when we see people practicing effectively, we usually describe it with words like will, focus, or concentration, like the proverb "Where there is a will, there is a way" (p. 13, 14), but these words don't quite fit. as author Daniel Coyle asserted in his book The Talent Code: Greatness Is't Born.It's Grown. Here Is How. In his book, based on observations of a football player training, singing along to a pop song, and a handful of others "Harvards at the fence." Examples (p. 11), Coyle argues that effective practice is not just described with words like willpower, focus or concentration, because they are then deliberately operating at the limit of their abilities, therefore they are wrong. And one way or another, to be wrong is to do better (p. 14). Coyle cites the collective talent of Brazilian footballers to illustrate his basic argument. Contrary to the conventional way of explaining this type of concentrated talent of Brazilian football players by attributing it to a combination of two genes and environment, i.e. nature and nurture, Coyle uses the fact that happened before and after the 1950s and finds the surprising answer is that Brazilian players have trained in a particular way since the 1950s, with a particular tool that improves ball handling skills balloon faster than anywhere else in the world. Coyle calls this kind of training deep practice, and then he shows that it applies to more than just football. (p. 14) Another way of showing his concept of deep practice is one of his experiments in doing so, as he says that "the best way to understand the concept of practice is to do it." I took this... middle of paper... and our current capabilities; to target the fight. Because struggling blindly doesn't help, reach for help. So our job is to find the sweet spot, as Coyle cited Björk's saying, to find the optimal gap between what you know and what you're trying to do (p. 19). There are also limitations, no detailed suggestions or measures that readers can apply to find the "sweet spot" ------at least the excerpt I read. We all know that there is an interesting point, but it is more important for us to apply it deeply to find it. We need detailed measurements and a guide to practice with. One thought I had while writing this review is that I will apply Coyle's concept of deep practice in my work as a teacher, in my daily life, and also share it with my friends, my students.
