I saw this list of 25 rules to grow rich by and thought it had some good points/ideas. Among those I thought were important were,

4. Your total housing payments should not exceed 28% of your gross income. Total debt payments should come in under 36%.

11. If you don’t understand how an investment works, don’t buy it.

18. The bestway to improve your credit score is to pay bills on time and to borrow no more than 30% of your available credit.

20. The best way to save money on a car is to buy a late-model used car and drive it until it’s junk. A car loses 30% of its value in the first year.

25. When you shop for electronics, don’t pay for an extended warranty. One exception: It’s a laptop and the warranty is from the manufacturer.
