Yeah, but it's bollocks. Too much grinding dulls your mental acuity. We're not talking about World of Warcraft where your score depends on how many times you press the button in the Skinner box. We're talking about real life where progress depends on understanding better ways to do things. A few years at a healthy, sustainable pace with work-life balance will leave you better at your job than a few years of demented grinding will.
