I don't think most people spend 2 hours a day on "learning and development" outside of work (you might consider getting a job where you can learn and develop more, if so). But even if you did, you can take a day off to do that. You're still at 60 hours of work, which is what the blog post references.
I have no idea what most people do. Most of my friends and colleagues spend 2+ hours a day working on side projects and/or learning new technologies.
Unfortunately, in my experience I've found in fast paced environments you learn the minimum to get the job done.
Sure I could switch companies every 18months in order to keep learning via work or i could add a ton of business value at my current company by working a more reasonable number of hours and focusing on my personal development in my own time.
