Business Insider and Yahoo News cover an interview-based discussion with dozens of FIRE (financial independence, retire early) investors focused on the strategy of “earning more.” Across the accounts, the central theme is that increasing income is treated as a core skill among people pursuing early financial independence. The articles describe how side hustles vary widely in day-to-day effort and time demands, even when they appear simple or low-friction on the surface. The reporting emphasizes that what seems like the easiest option is not always the easiest in practice once the investor factors in consistent effort, skill-building, and ongoing work needed to generate material earnings. While the sources do not provide a single universal side hustle or a definitive ranking of best options, they collectively suggest that FIRE-focused earners tend to prioritize approaches where time investment aligns with realistic income potential. The coverage frames the takeaway as a caution to evaluate both perceived difficulty and actual time requirements when choosing a side hustle.
