Wow, that's really interesting! I haven't actually read the book (and I didn't even know it wasn't a biography per se), but that line about "winning with your mind, not your time" has really got me thinking. What you said about breaking the cycle of clocking in and out makes perfect sense. Sometimes we get obsessed with the hours worked and forget that what's important is the value we bring, whether we're chess players, writers, or whatever. You've made me want to check it out; it sounds like one of those books that kind of shifts your perspective. Thanks for the recommendation!
