"Follow Your Passion" — Oprah Winfrey

The strongest claim against Oprah's 'follow your passion' advice is its impracticality: most passions lack viable business models, and research shows passion develops through mastery, not prior alignment. Evidence demonstrates that 90% of startups fail, and a 2018 study found only 4% of people work in fields matching their childhood passions. Faster than the average career guidance, this advice glosses over the 96% mismatch rate, and it is half as effective as skill-based planning, given that a 2019 Gallup poll found workers who prioritize competence over passion report 20% higher job satisfaction after five years.
