I sat down to read a book. An hour later, I had read three pages. That's because there was a reference to London and it made me think about an article I had read a few years ago (that I've read more than five times since) about the test taxi drivers in London have to take to become a licensed cabbie. I read half of the article, got on YouTube and watched two or three videos about it, then got on Twitter and tweeted about it.
My wife and I recently started a side-business (trying to ramp up the Business side of it now).
