<i>I’ve worked 80-hour weeks for the past decade (occasionally 100-hour weeks)</i><p>Wow. This if anything will screw you up. 12 hours of work + 8 hours of sleep per day 7 days a week leaves you with 4 hours for commuting, showering, making dinner, doing laundry, working out and relaxing.<p>Doing eighty hours per week can be wonderfully efficient - for a few weeks. After that you start to get sloppy, and soon you&#x27;re performing worse than those doing a 40 hour week. Work a not a sprint, and not even a marathon, and more like running around the globe because you like to run.<p>Work shouldn&#x27;t even be means to an end of becoming rich, and being rich without a respected job you&#x27;re proud of is boring and hollow. Unlike prestige, once your income or wealth exceeds the limit where you have to stress about money, having more money won&#x27;t make your life happier.
