Create a one-month expense fund before paying down high-interest debt. While mathematically suboptimal, this psychological buffer provides immediate stress relief and builds momentum, making it easier to stick to a long-term financial plan.

Common wisdom to rapidly pay off a mortgage is suboptimal. Due to compounding, investing extra cash—even if the return rate merely matches your mortgage interest—will generate significantly more wealth over time. One investment compounds up while the other debt amortizes down, creating a large wealth gap.

Wealthy people don't avoid debt; they use it as a tool called 'leverage'. They borrow money at a low interest rate to invest in assets that generate a higher return, effectively profiting from the spread.

The most effective debt-reduction strategies prioritize psychological wins over mathematical optimization. Methods like the "debt snowball" (paying off smallest debts first) build momentum and change behavior, which is more crucial for long-term success than simply focusing on the highest interest rate.

When prioritizing debt, focus aggressively on any loan with an interest rate above 8%. This specific, actionable threshold helps distinguish between manageable debt and 'financial bleeding' that needs to be stopped immediately, simplifying your repayment strategy.

The "DOLP" (Done on Last Payment) method prioritizes paying off the smallest debt balance first, regardless of the interest rate. This strategy creates quick wins and psychological momentum, making it more effective for sticking to a debt repayment plan.

As Mark Cuban advises, eliminating debt with a 23% interest rate is financially equivalent to earning a guaranteed 23% return on that money. Before seeking gains in volatile markets, the most certain and impactful financial move is to stop paying high interest to lenders, effectively locking in that return.

Contrary to common advice, withdrawing from an IRA and paying taxes to clear high-interest debt offers a guaranteed, risk-free return. This "return" from debt elimination can be financially superior to the potential, yet risky and unguaranteed, returns from keeping the money invested in the stock market.

The minimum payment is the most dangerous feature of credit cards. Paying just the minimum on a $5,000 debt at 20% interest can take 23 years to pay off and nearly double the total amount paid due to interest.
