The multitasking seems to be a way of life in our culture, but real productivity is a definite focus, and this is significantly.
As an exercise, try to set emphasis on one or two tasks today. Install the alarm for 15 minutes, and then focus on this task. This focus can allow you to delve into this topic, and not just look at it superficially. Not looking for perfection, you just have to be focused on performance. You will be surprised at how quickly you can complete the task in 15 targeted minutes.
