Research shows that, far from being an effective time-management skill, multi-tasking actually impairs memory, increases stress, and make us LESS productive. It can also make us feel exhausted, ineffective, and unsatisfied. That’s because people can’t effectively concentrate on more than 2 or 3 things at a time before they get confused and start making mistakes. By limiting the number of tasks we try to do at once, and doing each one little more slowly and mindfully, we can actually be a lot more productive in the long run, and a lot less stressed. Some time-management experts also suggest scheduling in time for things that help us recharge, like exercise and rest.
