Two types of collateral damage in your brain

In general i find context switches to be quite dangerous.

However, I waste ALOT of time during the work day.

There is a difference, however between deliberate time-wasting and the type of time wasting that actually is associated with something important.

As an example, here is a sequence diagram of the typical time wasting you might do during the day.

In the above diagram, i send a dumb text and start wasting time.  I start an entire dumb conversation with two friends.  In any case, as i get an interrupt "event X".  At that point, I can completely ditch the entire conversation, because it was a dumb text to begin with.  This means that there is no "collateral damage" from the distraction i started... The time wasting can end at any minute.

However, when you do something sort-of-important as a distraction... Here is what happens.

Now in the worst case scenario, you might get one of these cirtcular dependencies going, where the semi-important  task winds up being done half-assed.  Now... you have a circular web of retrying the task which occurs, which is also prone to interrupts.
