Your credit score affects the interest rates you're offered on credit cards and loans, can be used to vet your job application, and in some states may influence your insurance premiums.
Late payments also hurt your FICO score. And never, ever take out a cash advance on your credit card.
The last thing family and friends want is for you to spend money on them that you don't have or that you can't really spare.
If you are worried about job security and do not have an adequate emergency fund (ideally eight months' worth of living expenses stashed away in a federally insured bank or credit union), you need to focus more on saving money than paying down the balance on your credit cards.
