I'm no psychologist but I hope to see those in that profession read this article. I've noticed that many are quick to label a patient mentally ill and prescribe medication.

While I agree with the idea that, "consuming has a more immediate reward than creating," the need to be distracted isn't the only reason. We do want to be informed and reputable media outlets, for the most part, do want to inform. It is our inability to effective process the ever increasing amount of information out there. Maybe we need to take on less interests or maybe we need better filters (Google isn't cutting it?).
