Anders Ericsson Quotes in Grit
Ericsson generally finds that deliberate practice is experienced as supremely effortful. As evidence that working at the far edge of our skills with complete concentration is exhausting, he points out that even world-class performers at the peak of their careers can only handle a maximum of one hour of deliberate practice before needing a break, and in total, can only do about three to five hours of deliberate practice per day.
Gritty people do more deliberate practice and experience more flow. There’s no contradiction here, for two reasons. First, deliberate practice is a behavior, and flow is an experience. Anders Ericsson is talking about what experts do; Mihaly Csikszentmihalyi is talking about how experts feel. Second, you don’t have to be doing deliberate practice and experiencing flow at the same time. And, in fact, I think that for most experts, they rarely go together.
