My parents told me the same thing and they were right. But everyone's situation is different. Run the numbers for your specific situation before making a decision. There are good calculators online that account for all the variables.

The biggest financial mistake I see people make is not having an emergency fund. Before investing, before paying extra on debt, save 3-6 months of expenses in a savings account. This protects you from going into debt when unexpected things happen.

Don't make a big financial decision when you're stressed or excited. Sleep on it. The dealership, the realtor, the salesman all want you to decide RIGHT NOW because pressure works in their favor. Walking away is always an option.

If your employer offers a 401k match, contribute at LEAST enough to get the full match. That's free money — like a 100% instant return. Skipping the match is leaving thousands of dollars on the table every single year. Do that before anything else.

The simplest advice I ever got was: spend less than you earn and invest the difference. Sounds obvious but most Americans don't do it. Track every dollar you spend for a month — you'll be shocked where your money goes.

Pay off your highest-interest debt first — that's almost always credit cards at 18-22%. There's no investment that reliably beats paying off an 18% credit card. It's a guaranteed return. Knock that out before you even think about the stock market.
