Vivian Ezugwu knows a thing or two about hustle.
A full-time night shift nurse in Manhattan, she also picks up work as a school nurse during the day. Why? “It’s great to have an extra income,” she says. “It gives you a sense of comfort.” And in New York City, where rent feels like a second mortgage, it’s not just smart. It’s survival.
But here’s the twist: Vivian isn’t alone. She’s part of a growing tribe of Americans taking on side hustles not out of desperation, but as a strategic move. According to Bankrate’s 2025 Side Hustle Survey, over one in four U.S. adults have a side gig, and for the first time, the top reason isn’t to pay the bills—it’s to fund discretionary expenses like travel, hobbies, or passion projects.
Translation: Side hustling is going mainstream. And it's not just an economic trend, it’s a brain-smart way to build a more fulfilling, financially secure life.
Why Side Hustles Feel Good (and Smart)
Here’s the neuroscience behind it: When you take action toward something meaningful that you choose rather than something you must do, your brain lights up in all the right places. Specifically, the dopaminergic reward system (linked to motivation and anticipation) and the prefrontal cortex (your long-term planning HQ) get activated.
In other words, side hustles give you a sense of agency. You’re not just reacting to life. You’re building something.
And when that side hustle is aligned with your values, interests, or long-term goals, the brain releases oxytocin and serotonin, two chemicals linked to trust, social connection, and well-being.
So it’s not just about earning more money. It’s about feeling more in control, creative, and alive.
The Safe Path to Entrepreneurship
Here’s where it gets even more interesting.
A side hustle doesn’t have to stay “side” forever. Many of the world’s most successful companies, from Apple to Spanx, started as small side projects worked on during evenings and weekends.
Why? Because starting on the side:
Allows you to experiment without risk
Keeps your primary income stable while you test ideas
Gives you time to build skills, networks, and confidence
Helps you discover if you want to go all-in
It’s like growing a plant in a pot before transplanting it to the garden. Your brain favors this approach as well; it avoids the stress overload of “all or nothing” thinking and instead fosters a more sustainable path toward change.

Vivian Ezugwu isn’t just earning extra income; she’s living proof of how side hustles can support both financial stability and personal empowerment. While her side hustle might not be a business (yet), it demonstrates the mindset that fuels future growth: resourcefulness, resilience, and readiness.
Whether you’re saving for something fun, working toward a dream job, or simply looking to feel more energized by your daily grind, a side hustle might be precisely what your brain and bank account need.
