I'd say that EVERY time I sit down to work, I check a few websites as I'm settling in.  One of them is Facebook.  Just a quick glance.  And NOW I know why I never get anything done.

According to a new study published in "Psychology Today", just ONE SINGLE VISIT to Facebook can completely derail your productivity.

The researchers found that more than any other website, Facebook distracts your brain in a way you can't recover from.  You want to see if people comment on your posts.  You want to see what your friends are doing.  You want to stay up-to-date.

And because of that, even ONE Facebook visit is a gateway drug that throws your productivity off course.
