But having both an 8-to-5 day job, and dedicating time afterward to run an online business, was harder than she expected. Miccio was burnt out she said, and knew she needed a change. "If this brings me so much joy, and I feel so much stress from having lack of time to do it, then having a day job doesn't make sense," she said, explaining why she ultimately left her job in sales.From day job to influencer careerMiccio started her YouTube channel in 2011, posting videos like packing for sleepaway camp, what she got for Christmas, and high-school advice.She continued her channel into college, filming videos in her dorm room, and in her senior year, started a podcast, "Gals on the Go," with fellow University of Georgia student and YouTube creator Danielle Carolan.Shortly after posting weekly episodes, they signed with the major podcast network "Podcast One." Miccio records weekly episodes with Carolan, working with Podcast One and a graphic designer on branding and development.Read more: Lizzy Capri quit her day job at LinkedIn to become a YouTube creator and amassed 3.9 million subscribers in less than 2 years.

"It's hours here and there," she said. "Three hours on a Sunday morning to reply to comments, post a video, post on Instagram. The hours add up, but I absolutely loved it and in my head I don't even see it as work."But there's a lot more to an influencer career than what you seen online, she said.From conception, filming, editing, and promoting, YouTube creators do it all. Before she posts, she'll think about what the title, the tags, and "metadata," will be that will ultimately help the video perform well and reach the right audience, she said.Since leaving her day job, Miccio has hired two part-time assistants (college students in Boston) to help her take photos and run errands. She's purchased a coworking space membership, which she said will function as an office and as a place to network.Earning money online Without giving a specific amount, Miccio said she "earns a comparable amount online" to the day job she had in sales.When she announced she'd be leaving her day job, she said people were mostly concerned about her finances and how she would continue to support herself.But now that Miccio is a full-time influencer, she said she earns her money through brand sponsorships, YouTube AdSense, podcast ads, and merchandise sales. Miccio is managed by Slash MGMTand has a talent manager who assists her with securing brand sponsorships and other business opportunities.She received a degree in marketing with a digital emphasis from Georgia and said it isn't going to waste. She said having a degree in marketing has helped her understand how to better market her content to a specific audience, and scale her brand."This is a career nowadays," she said. "And it shouldn't be a shameful thing to be an influencer. It's an awkward thing to discuss but I think five, 10 years from now we are going to see a lot more people opting for things like this."For more on how influencers are profiting from their success online, according to industry professionals and creators, check out these Business Insider Prime posts:A 5-step guide to making the most money possible from YouTube video ads, with advice from top creators: We talked to industry insiders about how a YouTube creator could monetize their channel through ad revenue and the tactics influencers are using.How Instagram influencers land their first brand-sponsorship deals: Influencers and brand execs share their tips for landing that first deal.4 tips to getting your first 1,000 YouTube subscribers, according to a creator with millions of them: We spoke with entrepreneur Benji Travis on his four tips people could follow to get their first 1,000 subscribers on YouTube.Join the conversation about this storyNOW WATCH: Animated map shows how cats spread across the world Click here to read full news..
