David in Virginia Beach has $35,000 in credit card debt, an $800/month car payment, and a fiber splicing side business bringing in $2,000–$6,000/month. Dave's math: dump the car, work $6,000 worth of splicing, put $4,000–$7,000/month on the debt, done in under a year. The interest rate is irrelevant when you're attacking this fast.
