In November 2015, Alex Fasulo had been living in New York City for about a month. One morning, she left her apartment in the Bushwick neighborhood of Brooklyn, got on the subway and headed to her public relations job. After getting off the subway, she just kept walking.

“The day I quit my job, I felt a funny sense of rebellious freedom that I never felt in my life because I hated that job so much,” Fasulo, now 25, tells CNBC Make It.
