It's no surprise we spend money on the things we value. So the question is, how much would you invest in a decent hi-fi or sound system? Bear in mind that a good quality system will last a long time, so amortizing the investment over a period of five or even 10 years should be factored into the expense. The coffee's gone in a matter of minutes.
Let's see, at $4 a day, a $20-a-week Starbucks expense works out to $1,000 a year. You're not going to stop anytime soon, so Starbucks, or any daily beverage, could easily suck $5,000 to $10,000 out of your wallet over the next decade. And you thought high-end audio was expensive!
Of course, any sort of decent hi-fi wouldn't be all that wise an investment if music isn't important to you. But if it is, how much would you spend on one?
