Sean Gallagher, a.k.a. "Gladd," is a 31-year-old Twitch streamer and YouTuber, who often plays "Destiny 2."

Gallagher says the long hours and "high levels of ever-changing competition" can be "exhausting."

"This is a day-in and day-out part of the job," Gallagher told Business Insider. "This could also be seen as an upside and motivator to keep pushing. However, as you get more comfortable in your element, there are always newer, younger, and fresh faces entering the market."

Gallagher also mentioned how work-life balance can become difficult for "relationships outside of gaming," since "it's very easy to become so tunnel focused on building up your gaming name, that you can lose sight of the friends and family around you." Plus, it's easy to get sucked into the numbers game when it comes to streaming, like keeping track of your viewers and subscribers, since those heavily influence one's income.

"This can cause frustration, confusion, and a demotivating state of mind," he said.
