(CBS) -- Nine to five Tina Gong spends her days designing the website for a small marketing company. That job inspired her to turn her passion for designing tarot cards into a second job, also known as a side hustle.
A recent report found more than 44 million Americans have a so-called "side hustle." It's a way they can earn extra cash on the side.
Chris Guillebeau is the author of "Side hustle: from idea to income in 27 days."
"It's something that I can point to and say okay, I got my paycheck from my employer and that's fine and I love my job, but I'm also building something for myself as well."
Younger baby boomers, age 53 to 62, earn the most from side-hustling, pulling in at least a grand a month. But 32-year old, Jennifer Li, claims her side job, organizing trips for young professionals, is equally lucrative.
An event planner by trade, Li says there's an added benefit.
"I get to travel for free which is the biggest perk. Building a community of people that I admire and love. That's just the intrinsic value that I go for."
Tina spends about three hours every night crafting intricate designs on her tarot cards, then sells them online starting around $45.
Now, Tina is all about living in the present, happy with her day job and her side hustle.
