This is my favorite trick because it requires almost no effort. Ask a parent, partner, or close friend with good credit to add you as an authorized user on their oldest credit card.
You don’t even have to use the card. Their positive history (like on-time payments and a low balance) gets added to your credit file. It’s like being the plus-one at a fancy party—you get all the benefits without the work.
Just make sure their credit habits are solid first. One friend did this for her brother, and his score went from 640 to 700 in three months.
Never, Ever Be Late (Even by One Day)
Payment history makes up 35% of your score—the biggest chunk. One late payment can drop you by 50 points or more, like a flat tire on a road trip.
Set up automatic payments for at least the minimum due on every bill. If you’re forgetful like me, put a reminder on your phone for three days before the due date.

Call it your “credit score alarm clock.” I miss a credit card payment once, and my score fell by 40 points. It took me six months to get back to where I was. Don’t be me on that one.
