The biggest financial mistake is not a bad investment. It's lifestyle inflation. You earn 5,000 RON → spend 4,500. You get a raise to 7,000 → your expenses increase to 6,500. The proportion remains the same, but you missed the chance to invest the difference. The alternative: with each raise, invest at least 50% of the difference BEFORE adjusting your lifestyle. The rest — enjoy. Earning from 5,000 to 7,000: +2,000 RON → 1,000 invested monthly × 7% × 10 years = ~173,000 RON → 1,000 spent monthly × 10 years = 0 RON Both options make you "happier" in the short term. Only one makes you free in the long term.
