What Every Purchase Really Costs Your Future Self
Every time you spend money on non-essentials, you aren't just losing that amount—you're losing everything it could have become over 20 to 30 years. A $5,000 impulse purchase today doesn't cost $5,000. Invested at a 7% average annual return over 25 years, that same $5,000 grows into over $27,000+ in retirement capital.
