If you feel that you have to do three things at once, then you might find it really difficult to do so. In order to be productive, you need to do many things at once-and effectively! You can't just rush things for the sake of having them finished. Multitasking is a very defined and complex art. Your brain processes are maximized, but if you don't know how to effectively multitask, then it might get overloaded. Although taking things one at a time would be ideal so you won't get messed up with details and other data, multitasking can be efficient if you know how to effectively do it.

Plan Ahead
It becomes important that you know what to multitask before starting out. This will accustom your brain to accept the workload beforehand. Make sure you stick to these tasks and don't add anymore! Effective planning is always the first step in a rigorous process such as multitasking.

Group Related Tasks
You may be performing four or five tasks and two of them involve reading a book and writing some articles. Put those two together so you can reduce the stress your brain needs in order to perform the function. Reading and writing are related tasks because they both function on language and comprehension skills that you have. If you put these together, you can save yourself a lot of trouble adjusting to something new like solving your finances.

Prioritize
Once you've planned ahead and grouped related tasks, what is it you do first? Naturally, you consider factors such as deadlines and acquaintance. Surely, you want to get the tasks that have to be done in the next hour done as soon as possible, right? And, you would rather do familiar tasks than ache yourself trying to figure out how to do something difficult. These two factors help you put your priorities. Start with what you're familiar with. You want to get those done so you can focus more on what you don't know much of.

Make a Mental Narrative
You will find out that you work better if there is a sense to your multitasking endeavor. Come up with a mental story to it all; it can help you smoothly adjust to the tasks at hand, saving you the time of mental lapses and less productivity. Mental narratives give your brain a whole overview of what is supposed to happen.

Keep the Drive Going
Don't stop until you're done. Multitasking is a very tedious task so make sure that you don't leave tasks unfinished to take rest. Don't stop if you haven't finished writing your article and not checking all of the emails. This will throw you into a mental shock once you sit back. You will notice that you have lost your creative edge and organization for what emails you need to respond to. Stop only if you've done a set of tasks. This will help you adjust better and focus more into the task at hand.
