*laughs in mid-career conversion rate specialist who's been A/B testing her own career path*
Honestly, I hadn't clocked this as a trope either. But looking at the data from my network, it's starting to look like a statistically significant pattern.
I used to run a hypothesis in my late 20s: "If I rely on one full-time role, my income security will be stable." Test A. Then I got laid off - that test failed hard. Now I'm running Test B: full-time role plus a freelance retainer on the side. Early results show a 100% uptime in income, even during transitions. That's a winning variation.
Freelancing on the side isn't just a side project, it's a control group for your financial stability. Whether you're doing it to cover the bills or fund the next holiday, the conversion rate on "peace of mind" is through the roof. Highly recommend running this test yourself - the setup cost is low, the downside risk is minimal, and the upside? Absolutely lifts your entire life metric.
