The article assumes that you don't find your work interesting enough to keep your attention focused for a prolonged period of time. Maybe it is better to try to understand why it is not interesting and find ways to make it actually catching rather than figure out workarounds. Because why should we spend time on things we are not interested in?
However, I don't always enjoy my work. If I'm stuck o the same thing for prolonged amounts of time or if things keep not working out (eg fixing a bug only to find another and another and...). My work also requires that sometimes I do stuff that I don't enjoy. I've yet to come across a job where I enjoy 100% of the tasks that come my way.
I've also noticed that there's a difference in enjoyment between tasks that I do because I have to and tasks that I choose to do because I feel like it. Both tasks could actually be the same thing, only one I decided I wanted to do and the other external factors decided that I should do the task.
For example, one day I was feeling frustrated and burnt out by work and after work I did a little programming that was more-or-less the same kind of work that I do in my job, but I did it for myself for fun. And I felt refreshed.
