I am all for being cheap (driving used cars, drinking rail liquor, shopping at TJ Maxx etc.) but this is not the key to getting wealthy. Bill Gates (or any self-made wealthy person) did not get rich by shopping at Aldi. He hustled, and was always looking for ways to grow his income.
Stop trying to figure out how to save a buck, and start figuring out how to earn $2 (or $200). Your personal finances are like a small business, and there are two sides to the equation. Income in is just as important as spend out. You cheap bastard.
