You might say that, but after several months of a form of Tibetan buddhist meditation, I extended my attention span to well over five hours. I found I could retrain my mind to be silent and do what I wanted.

The form of meditation is detailed in the book "Turning the Mind into an Ally" by Sakyong Mipham and Pema Chodron.

Are you happier than you were when you started? Are you more productive? As someone who was recently diagnosed with ADD in my mid-30s, I am weary of medicating and would really like to find a natural approach to achieving focus and through that, happiness.

If you start looking, you'll find a pretty unanimous agreement of the benefits of meditation both from a research and an anecdotal perspective.

However it's not a practice that, at least initially, benefits much from doing extensive research or setting goals. Just let your curiosity guide you. Here's something that you can read in 5 minutes to get you started: http://zenhabits.net/meditate/

Thanks for the starting point. The 5 minute read is most important for someone who has a limited attention span. :)
