Overusing Plastic
Just as avoiding credit cards is bad, so is overuse of plastic. Aim to keep your usage below 20% of your limit - so if you have a $5,000 credit line, keep your balance below $1,000. Pay off the balance monthly whenever possible; no one wants to pay interest on that steak dinner you had back in July. If your partner is quick to pull out the plastic, make sure you sit down together to look at the bill each month.
