Though computers are the key to modern productivity, they are also the biggest distraction from our work. Whenever you sit down to write, prep a spreadsheet, or produce that vital PowerPoint, the temptation to open up Facebook or Twitter is palpable. How many hours of productivity have you lost looking at useless Internet lists? In the 1890s, this wasn't a problem. The thinking man's work only involved the man, his typewriter, and his unrelenting focus. This also meant that one typo was enough to force you to rewrite the entire thing, but that gave you all the more reason to focus. That being said, since you weren't balancing hashtag games and Candy Crush with the task at hand, we imagine typos were far less common.
