Multitask! Multitask! Multitask!

I used to think I could multitask. Back in the 6th grade or so, I remember "simultaneously"drawing, watching TV, and doing homework. Of course, I really wasn't doing all that at once, but I was certainly trying. All the work got done in the end, so I figured I could keep on "multitasking." I usually kept it down to just watching tv and doing homework, but I did it all through high school.
Recently, I've gotten about half way to kicking the habit. Now that all my work has to happen on the computer (save the sketching parts), my workstation is the same as a huge source of entertainment. The Internet, Netflix, and tons of articles are just one 3-finger swipe and two clicks away. It's so easy to get distracted by a thought and end up on browsing the internet. Sometimes I'll even run a Netflix show I know well, like Bob's Burgers or Archer in the background and just listen to the show as I work. I say that I need the "background noise" to work, but that's not really the case. When I work in the Campus Life Office, I often work in silence, or just with music, and that's when I'm at my most productive.
Of course, these are terrible habits that I need to break. One of the books recommended to me: 99u's "Manage Your Day-to-Day," has a whole section on focus and breaking what psychologist Christian Jarrett calls the "multitasking myth." His article is about the way we lose our flow when we lose our focus and multitask, since we aren't really doing two things at once, but bouncing quickly back and forth between two things. Any time we turn our attention away from the task at hand, we fall down a "rabbit hole" of distraction.
The biggest issue for me lies in the fact that I need to use a computer to do a good portion of my work. "Even if you have cast iron willpower," Jarrett writes, "the mere fact that the internet is lying in wait on your computer takes a toll on your work performance." We have to do our work on machines that are the gateway to distractions, it's likely we'll end up there at some point.
So what am I doing to fix this? Well, for starters, I've taken to shutting off the wifi on my computer when I have to get work done. This doesn't alway work, since I do need the internet for some of my work, but it does help me to focus. I've also begun weaning myself off of Netflix with music and podcasts (particularly This American Life, an NPR podcast). Since there are no visuals, I'm not nearly as tempted to change my focus to it fully, I can just half-listen to it as I work. I'm a work in progress, but I'm definitely improving.
