No – there is no such thing as multi-tasking!
Now, there are times when you must give your attention to multiple tasks. Be aware that you are not multi-tasking, you are attention-switching, and take this into account when you switch your attention to another task. At the very least, you will need to take time to “catch up” on the task before you perform some new action related to it.
My boss just shed some light on this. Great epiphany.
