Nice artice :
As much as workaholics like to claim that they’re superior because they work more hours, don’t listen to them.
Workaholics do work more hours than the rest of us, but they don’t work smart hours. They may sit at their desks forever, but that doesn’t mean that they’re using their time well 100% of the time. In fact, odds are good that the quality of their work is lower because they work in long, uninterrupted sessions that are a big drain on their brains’ mental energy. As the quality of their work drops, so do their productivity and their morale – resulting in one overworked, unhappy worker.
