Forget Multitasking
The ability to multitask was formerly hailed as a great method to make the most of one's time and do more in a day. However, people eventually realized that their speed and accuracy, not to mention sanity, often decreased if they were doing calculations while holding a phone to their ear.
The majority of people find that dividing their attention doesn't work effectively since it left them feeling "frazzled". Your efforts will be wholly concentrated on accomplishing more in less time, with total disregard for every other aspect. "Multitask" is not always a sign that you're getting the most out of your time to do a lot of tasks in a short amount of time. It means the complete opposite. You may be working more quickly if you focused on one activity at a time. Try another cognitive method, such as chunking, to keep on top of your tasks instead of multitasking.
