This teenager started playing video games 18 hours a day. Now he makes more money than most adults.

Griffin Spikoski spends as much as 18 hours a day glued to his computer screen playing the wildly popular, multi-player video game Fortnite. His YouTube channel -- where he regularly uploads videos of himself playing the online game -- has nearly 1.2 million subscribers and more than 71 million views; figures that have netted him advertisers, sponsorships and a steady stream of income. Last year, that income totaled nearly $200,000. The healthy sum -- more than enough to comfortably raise a family in most American cities -- is all the more impressive considering Spikoski is 14 years old. Still, he approaches video games the way an elite student athlete would approach a sport like football or basketball: when he's not playing, Spikoski, who goes by the name "Sceptic" on YouTube, completes school work online.
