How many hours do you work each day? If you’re like most of the U.S. working population, you probably think you get a solid eight hours in. That’s 40 hours a week. Around 1,800 a year (minus 2 weeks’ vacation). Not too bad. The problem with this kind of thinking is that just because we’re at work for eight hours a day doesn’t mean we’re doing eight hours of work. (In fact, pretty much every statistic puts that number significantly lower.) Assuming you have more time than you do is the quickest route to stress, overwork , a lack of productivity , and eventually, burnout .
