Yes, ever since I've read The Snowball I've picked up Warren Buffett's habit of automatically multiplying the cost of all purchases. Even though I probably can't meet his returns I am young enough that I can sqfely multiply everything by at least 5. So a $4 cup of coffee is really $20 cup of coffee with the growth I've lost.

Now, on the flip side, anyone stuck in debt, especially in credit card debt, you wish that cup of coffee only cost $20.
