Roughly half of Americans don’t take their vacations. Before you decide to become one of them, think again. You’ll actually become less productive if you don’t take time off. The human brain is not designed to work all the time, which is why taking at least one day completely work-free every week is important for both brain health and productivity. Similarly, taking time away from work--at least a week, once or twice a year--will drive better productivity the rest of the time. It’s especially important for small business owners whose jobs depend on their creativity or strategic skills, since most people do their best thinking about the big picture when they get away from the office for a while.
