And she got it all done within a year after turning the television off. I'm not saying that I would necessarily trade The Americans and Veep for grinding marathon training and a postgraduate degree, but Burrell makes a compelling case. Burrell was already rapidly improving--she had already cut her PR from a debut north of 4:00 to running in the 2:50s. But she hadn't qualified for the Trials yet, and after 11 months without television, she slashed her PR by ten minutes and ran 2:42:13 in December 2014 to punch her ticket.
She writes that "Almost immediately I noticed I was enjoying my weeknights more. I didn’t automatically collapse on the couch only to look up hours later, surprised so much time had passed...Sans TV, evenings seemed longer: I got more chores or work done, spent time piddling on the Internet or read. And I actually got to bed on time." Just that one factor alone--getting to bed on time--is enough to say that giving up TV made her faster. (And it's even easier to imagine it being helpful in her academic and writing careers; of course turning off the TV helps you do homework and get writing done.)
This isn't quite on par with former NFL running back LenDale White saying that he lost 37 pounds in six months by giving up Patron tequila. But there is a 100% chance of high school and college coaches admonishing their athletes with this article at practice this week.
