>For example, a recent study found that Americans work 25 percent more hours than Europeans, and that U.S. workers tend to take fewer vacation days and retire later in life. But for many, simply working hard doesn’t actually lead to a better life. using "pure" hours is weird way of measuring "hard work" In games like League of Legends there are players with like 6k hours and they stay around lowest ranks, where they should be way higher, but that's just game, they may not care about rank or stuff putting effort "blindly" is not optimal strategy ___________ who's doing more hard work - person who sits at warehouse for 9h day or person who sits at warehouse for 8h day and then learns for 1h e.g programming/math/physics/whatever in his free time? I'd say 2nd one is way harder
