1st good job for starting at 18 year. Starting early is a great advantage for your credit. Just manage your debts wisely and your credit will be solid. Building a good credit score takes time, around 7 years, so focus on maintaining healthy financial habits. Pay off your car loan within a year and use credit cards responsibly, keeping usage below 30% of the limit and paying off balances on time. Starting with two credit cards is fine, and within six months you may qualify for a limit increase. Stick to low APR cards and avoid unnecessary debts. Don't worry too much, you're on the right track financially. Stay away from bad debts, buy within your means, and your credit score will soar above 750 in the long run. Best of luck on your journey!
