Credit Card Rules Every Millennial Should Live By

Moving on from the Dave Ramsey community to the FIRE community often comes with a shift in mindset about credit cards. 

I'll admit, I definitely jumped on the credit card hating bandwagon when I found myself in debt in my early twenties. And it was true, at that point in my life there really wasn't a good reason for me to have credit cards.

Later as my income grew and my financial responsibility improved, I thought long and hard and decided that in many circumstances credit cards aren't completely a bad thing.

In our family, for example, we primarily use credit cards to rack up travel rewards. And because we are always able and conscientious enough to pay off our balance monthly, we are able to travel for nearly free several times per year.

That alone is worth it for me to open up cards. Of course, we also follow a few basic credit card rules to make sure we always stay in the green.

credit card rules to live  by

#1. Check Your Credit Score Every Month

This one only takes a minute, and it's super easy! Checking your credit score each month is so important. I use Credit Sesame because it's free, simple, and it monitors my account for me.

One of the biggest reasons to check your score monthly is to catch fraud.

Just a couple of months ago I found out from my Credit Sesame account that one of our cards had been compromised and the thief had racked up $10,000 on our credit card account. 

Thankfully I caught this quickly and when we contacted the credit card company they were already fixing the issue.

#2. Always Pay Off Your Balance Each Month

This point should honestly go without saying, but you absolutely must pay off your balance each month to avoid paying interest and getting sucked back into the debt cycle.

I highly recommend setting up your credit card accounts to be automatically paid off at the end of each month without you having to manually go in and do it.

If you're having trouble paying off your balances, it's time to ask yourself why.

Are you running out of money at the end of the month to pay it off? If so, you are overspending on your card?

Are you forgetting to pay your bill because you're super busy? In this case, I'd recommend either setting the payments on autopilot or setting up reminders on your phone to make sure they are paid on time.

#3. Make Sure You Have An Overdraft Fund Before You Open New Credit Cards

 Another tip I highly recommend is to have a small overdraft fund before you start using credit cards. This is great safeguard to make sure you always have the money to pay the balance off.

Of course, it's also important to make sure you aren't overspending and that you budget appropriately. That aside, having a few thousand dollars in savings that you could dip into if needed is a great fail safe.

#4. Get Travel Rewards From The Credit Cards You Do Open 

This one is a big one for us, because we love to travel! What's the point of using a credit card if you don't get something out of it? 

Of course, if you aren't a big traveler you will probably get more benefit from using cash back credit cards.

Either way, make sure you get flight rewards or hotel points or cash back from any card you sign up for. 

credit card rules

When searching for a travel rewards credit card, I always look for a few things:

  • The card should have a large sign up bonus
  • The card should have a reasonably low minimum spend to get the bonus 
  • The card should have a zero or low annual fee (less than $100)

I've found that American Airlines Citibank credit cards often meet these rewards criteria.

Here's a helpful hack many people don't know to help you get as many miles as needed for your next big flight.


Not only can you sign up for a personal card, but if it exists you can also sign up for a business card to help you get even more miles!

For example, a few months ago I signed up for the American Airlines Aviator card and the American Airlines Aviator business card.

Both cards had only a $1 minimum spend, so I was able to get 100,000 miles for the cost of two $99 fees and a couple sticks of gum. These miles have covered a domestic round-trip flight plus a round trip ticket to Europe we will be using this summer. 

Don't have a business yet?

Lots of side hustles qualify as businesses when you open up business credit cards. Keep reading below to find out some great side hustle ideas.

What To Do If You Are In Credit Card Debt


Now I know I just spouted off a few of the perks of having credit cards, but things change if you already have credit card debt! 

If you do still have credit card debt laying around, here's what I recommend.

  • Don't open any new cards!
  • Cut up the ones you have so you stop using them. (Or freeze them in a block of ice)
  • Use the snowball method to pay down your balances.
  • Use Acorns to save money for extra payments.

How to Find A Side Hustle to Pay Down Your Credit Cards Faster

Starting a profitable side hustle is one of the best ways to pay off any credit card balances you still have. Many of them can earn you upwards of $1,000 per month, which will pay off just about any credit card balance crazy fast.

There are a million different side hustles you could try, but I thought I'd give you a few ideas here.

Start A Profitable Blog

If you enjoy writing and find that you often have a creative streak, blogging might be the perfect side hustle for you!

Even better, many blogs that start off as passion projects turn into a full-time income, so if you've ever wanted more time to spend with your kids or you simply want to get out of your office job, now is definitely the time to start working on a blog. 

That being said, creating a blogging income isn't quick. Blogging takes a lot of time and hard work before it pays off, but when it does, it can pay extremely well. (Many bloggers make $10,000-$50,000 per month!)

If you need extra income quickly, I would definitely suggest choosing one of the side hustle ideas below. But if you're looking for a long term project that has the potential to become your full time job, blogging is a great choice and my personal favorite.

Restore Old Furniture and Flip It

Maybe this is just a hobby of mine, but I love taking rundown furniture finds from Craigslist and giving them a makeover. This is how I've furnished much of my own home, plus made a little extra side income as well. 

The key to making money flipping furniture is to choose projects that won't take a long time to complete. If it can be done in an hour or two, it's likely a good bet!

And when you go to sell your piece, look beyond just listing it on Craigslist. Buy sell trade groups on Facebook can also be a great place to list your furniture!

Become A Dog Walker/Pet Sitter

If you like working with animals, dog walking and pet sitting is a great way to make plenty of extra cash. Pet care providers on Rover often charge $15 to $20 or more per 15 minute appointment, so even a couple of appointments per day can add up fast.

In fact, lots of dog walkers and pet sitters make more than $1,000 per month playing with pups and doing pet sitting appointments part time. Many even go full time with it after building up a solid client base! 

Here are a few of my best tips for a successful pet care side hustle:

  • Bring an extra collar and leash. You never know when you'll suddenly need it!
  • Ask the owners about any aggressive neighborhood dogs that could be loose while you are walking.
  • Include plenty of pictures in your Rover profile to help you stand out and gain more clients.

Provide Childcare for Other Parents

Child care is one of those things that is always in demand. If you have a little one at home and want to make some extra income, offering to provide child care for one or two more kids might make perfect sense with your schedule.

I know plenty of moms who provide child care for other neighborhood kids by networking in parenting Facebook groups and other in-person moms groups.

Depending on how many hours you are willing to provide, you can easily make $1,000 per month or more on the side. 

Grow Plants to Sell on Craigslist

Have a bit of a green thumb? One fun and easy way to make extra money is by growing plants from seed and selling them on Craigslist. 

This could be things like succulents, tomato plants, herbs, and more. Start them from seeds in your windowsill and then separate them into 1 or 2 inch pots after a few weeks.

Once your plants are a few inches tall, you could easily sell them for a few dollars per pot. I recommend going with plants that are season appropriate. 

Tomato and pepper starts are great at the beginning of summer. Succulents are pretty much appreciated year-round. And fresh herbs are always sought after in the spring and summer!

Airbnb Your Spare Room

Have an extra room or property that isn't in use?

Airbnb is such a cool way to make extra money!

You'll get to meet people from all over the world, talk to them about their travels, and make good side money doing it. 

I've stayed in many Airbnb's while my husband and I travel, and I love them. They are always so much nicer than staying in a hotel, and much cheaper. 

The plus side for you is that Airbnb hosts can get paid extremely well.

Prices depend on your area and the space you have to offer, but you'll find that if you can book out most of the days each month you'll easily clear $1,000-$3,000 per month.

You can get $40 off your first Airbnb stay to see how it all works here.

credit card rules


Credit cards can absolutely be a positive financial tool if they are used in the right way. The key, of course, is to make sure that you reap the benefits from them (travel rewards, cash back, etc) without succumbing to the negatives (interest). 

And if you are in credit card debt right now, cut up or freeze all of your cards right now and get to work on some side hustles to pay those babies off FAST! Credit card debt is definitely an emergency, so treat it like your hair is on fire and get rid of it. You'll feel so much better!

So much good advice! We all need to be careful using credit cards.

Crickette, The Things I Have to Say - November 25, 2019

Credit Cards are good and bad, depending on how it is used. #2 is so important. One should really pay the entire balance if they do not want to fall into debt.

My dad would always say, you have to live within your means. A credit card is not magic money. It should not be treated as such.

    shesgotcents - December 6, 2019

    Your dad is a smart guy! I love that. “It’s not magic money.”

Kevin Akidi - November 25, 2019

These are great tips that should be followed by all. It is so easy to accumulate credit card debts if we do not practice good credit card habits.

I love that you not only gave some great tips for using credit cards smartly, but you also gave some great insight into solving any existing money issues. Thanks!

Shayla Marie - November 26, 2019

We’ve had a credit card for years, and we always pay it off every month. We’ve never not done this! We are a big family of 8 too. We have to say no to so many things (especially since we homeschool and pay for our kids curriculum out of pocket). It’s hard often! But it’s worth it. The only thing we are in debt for is our home. I really love the suggestions in this post, even though we don’t need to pay of CC debt I am ALWAYS looking for more ways to earn income! I’ve never thought of some of these ideas before! They are brilliant! Thank you for this post! I loved it!

    shesgotcents - December 6, 2019

    That is incredible Shayla! I’ve always been interested in learning more about homeschooling. Sounds like you have a great system in place.

Mila R - November 26, 2019

May I use it even if I’m not a Millennial? I love these!

Arunas - November 26, 2019

Blogging is great! Yes, I agree that it takes a lot of time and hard work before it pays off, but when it does, it can pay extremely well.

Monica - November 26, 2019

I often times wish we had a credit card that rewarded us with travel points. However we’re currently working on paying off our debt. I appreciate all the side hussle ideas to bring in some extra cash!

Diana - November 26, 2019

I love using credit cards. They are often safer than debit cards. You just have to be smart and don’t spend more than you have. I always pay off the balance ASAP. Plus, using them right also saves you money as many give cash back or other rewards, like travel. Plus you kind of need them to build up your credit score.

    shesgotcents - December 6, 2019

    Yes, the cash back is such a nice perk if you use it wisely. We like using our cash back for vacations, it always makes the trip a bit sweeter 🙂

Sarah - November 26, 2019

Only using your card for what you can afford and paying it off every month is huge.

Sadiq Saleem - November 27, 2019

Amazing I do about rules for credit cards😊
