A woman who quit her job as an investment banker now earns just as much traveling the world on her own

In March 2012, Kristin Addis quit her job as an investment banker in Southern California.

"It was hard for me when our paid time off was only 14 days per year," she tells Business Insider.

"We'd go to the office puking our guts out because we didn't want to use our vacation time being sick. I felt back then like even if I wanted to, in that 14 days, I wasn't really allowed to take it all at once. I felt like 'What is this money worth if I don't have the opportunity to spend it on what I want?

"I thought there had to be more to life than that."

So she set out to find it.

Less than a year later, Addis bought a one-way ticket to Bangkok, planning to travel overland through Southeast Asia. Since then, the now 30-year-old has largely stayed on the move, documenting her journey through her blog, Be My Travel Muse, and sharing the expertise she's gathered in her book, "Conquering Mountains: The Guide to Solo Female Travel," produced with Nomadic Matt's Matt Kepnes.

Below, she talks about the new life she built traveling the world: what it looks like, the reality of working on the road, and how she affords it.
