You could circle the world at least dozen times just by stringing together all the words that have been written about productivity.
In particular, managing information overload in a social and new media era is a topic that never ceases to draw the masses. There isn’t a day that passes that I don’t see at least a post from someone lamenting how they simply can’t keep up anymore, or keep track of what they have to do, or how they’re getting buried in information but not finding anything valuable out there. It happens to the best of us.
