My credit card debt hit $12,000 last year, and I've been wrestling with whether paying it off aggressively or investing spare cash is the smarter financial strategy. A finance buddy insists that earning 8% in index funds beats the 5% interest on my loans, but that assumes I'll actually stick to investing and not just spend the extra. Right now, I'm leaning toward paying down debt first for the psychological win, but what about those who have low-interest mortgages and huge retirement gaps? Should personal finance rules really be one-size-fits-all, or does the right answer depend on your personality and life stage? I've read conflicting advice from experts, so I'm curious how others have made this call.
