Actually, there are ways to learn to avoid multitasking. Studies show that multitasking does not get any more work done. Finishing a task before starting the next task is just as productive as multitasking, in some cases, more productive as the quality of the result can be better.

This does not mean one never switches between tasks. The point is to find a stopping point for one unfinished task before moving to the other task, finishing it then returning to the first task. The concept of having multiple tasks being juggled in the mind is counter to good results.
