Final answer:
The textbook does not recommend ignoring timely bill payments and using excessive credit; managing these well is key to careful credit card use. Credit and debit cards do not change the quantity of money available, similar to how more checks do not increase account funds. Healthy credit usage involves spending within limits and tracking expenses.
Step-by-step explanation:
When discussing the use of credit cards cautiously, the textbook advises against certain practices. It is not recommended to ignore the importance of managing your credit effectively. This includes ensuring you pay all your bills on time and being careful not to use too much of the credit that is available to you. It's vital to understand that having many credit cards or debit cards does not increase the real amount of money at your disposal, similar to how printing more checks does not increase the funds in your checking account.
To maintain a healthy credit score and keep your finances in check, it's necessary to use credit cards prudently, keeping track of spending and not overextending your credit limits. Rewards such as miles for air travel, which some credit cards offer, should not drive one to overspend but should complement efficient credit use and spending within one's means.
