Does it sometimes feel like you're working a lot, yet you can't get anything done? Don't worry, you most certainly are not alone. I also used to suffer from a sickness I like to call serious multitasking. It's quite closely related to the lack of concentration, idling and running aimlessly. I've come to the conclusion that serious multitasking seems to be on the increase, because for one information worker there simply are too many things to do and follow simultaneously.
