8. Avoid using credit cards
When you make a lot of money, it's easy to get tempted, especially if you have a credit card at your disposal. You might think you can quickly pay off your credit card bills, so you use your credit card when you need instant cash for a wide range of purchases. Unfortunately, that practice can lead to credit card debt.
Since a credit card is easily accessible, it can be challenging to monitor how much you've spent unless you actively track each expense. Before long, you may have accumulated debt beyond your paying capabilities.
If you want the cashless convenience that a credit card offers without the fees, you can try using a debit card or an e-wallet to help you with your spending needs.
