If money is becoming more and more of an issue in your life, sometimes it helps to just get a kick in the pants. This article from Yahoo Finance will force you to take a cold hard look in the mirror!
I feel pretty lucky that these aren't serious issues for me. I am rarely an impulse shopper and in fact will often "wait" until I just don't want something anymore. Or have forgotten about it...if anything I tend to be one of those annoying, "Man...I need some new tennis shoes..." people who will just continue to say that and not ever buy new shoes!
I do use my credit card, but I keep the balance low and to a point that I know I could pay off completely if I had to; I don't always try to because the card has a very low interest rate and I make way more than the minimum payments on it when there's a balance. Mostly this article seems to be aimed at those of us who think "things" will make us happy. Here's the thing: they won't. Those things are just filling a void and emptying your bank account at the same time.
Listen to the words of Voltaire: I've decided to be happy because it's good for my health.
