Think about this in a different light. Society has become more interrupt driven due to "live" streaming of items, aka social media. It becomes very challenging to stay focused when you receive a text, tweet or e-mail every 5 minutes. It isn't a problem caused by the inability to stay focused, it is a problem caused by the level of interruption in society.
Many of those with ADD/ADHD are some of the brightest individuals out there. If your brain can process inputs fast, it WANTS to process inputs fast. If your brain cannot process them fast, you will likely get distracted.
Think about the animal kingdom, which we are a part of. If a cheetah or game animal had high ADD/ADHD, they would be more likely to survive because they are aware. That flicker out of the corner of your eye, may be a predator and noticing it may have just saved you from becoming lunch. Which, is precisely why I call ADD:
Awareness Distraction Disorder
Hope that inspires an alternate direction to the conversation. Enjoy!
