One Task at a Time: Why Multitasking Fails
Having a plan is another issue in time management. This plan contains the tasks which you should do from morning to night, and it needs to be listed serially or in any orderly format. In case you haven't prepared such a text, it won't be weird if you fail in time management.
It's better to have a plan in different formats: one in alphabetical order; one in terms of time, for example what you are supposed to do at 6 o'clock; and a third list of important tasks which somehow must be accomplished, come hell or high water. Software is quite helpful in preparing a To-Do list.
Multitasking is the reason behind spending too much time on tasks and lack of concentration. While preparing your To-Do list, notice that you need to do one task at a time. Planning to do multiple tasks at the same time is neither an accomplishment nor a logical action. Concentrate on one task and accomplish it. Then go after the next one.
People who multitask have to keep putting off their tasks, and this postponing becomes a habit. Furthermore, they do tasks without concentration, so they have to spend a great deal of time doing multiple tasks. In the end, none of those tasks is properly accomplished, which makes these individuals unmotivated and drains their energy.
Eliminate from the list what stops you from doing important tasks and makes you diverge from your main path. For example, if you have an appointment with someone after an important meeting, but you have no idea how long the meeting will last, remove the appointment from your list because it will affect your performance in the meeting.
