Here is what I've learned about the concept of 'financial security' vs 'financial independence' and why I think the distinction matters.

Financial security: having enough buffer — emergency fund, insurance, stable income, no high-interest debt — that normal life disruptions don't become financial crises. This is achievable for most people within a few years of focused effort.

Financial independence: having enough invested wealth to cover all living expenses indefinitely without earned income. This takes most people 15-25 years of consistent effort.

The mistake I see: people skip straight to 'I want to achieve financial independence' without first establishing financial security. They invest before having an emergency fund, carry high-interest debt while buying index funds, or skip insurance to redirect cash to investments.

Establish financial security first — it's the foundation. Then work toward financial independence. Doing them in reverse order means a single emergency can unravel years of investing progress.
