Consumerist has a good post on ways smart people waste money.
Lets see how I stack up. Currently offending numbers:
1) Forgetting To Pay Bills
As hard as I try at least once or twice a year I make some kind of a goof up and smack my head against the wall when I find out.
2) Bank Fees
I've gotten screwed by the $5 ATM surcharge fee for withdrawing money in China, Europe etc. I've also paid the credit card bill with the wrong checking account causing a cascading series of fees that made my lose close to $100 bucks when all was said and done.
5) Subscriptions
Recently gotten rid of a few
6) Letting food spoil in the fridge
I will admit to that nice cheese I purchased at Whole Foods to serve when guests that were never invited didn't come over and I had forgotten about the cheese.
7) Wasting Energy
We are actually pretty good about this, but could be better.
9) Buying DVDs you will never, ever watch, or books you'll never read, or clothes you will never wear...
Guilty
10) Paying too much for cable
Semi guilty. Lora and I have been on basic cable for a year now and haven't looked back. We get all the HBO shows on DVD from Netflix whenever they get released.
There should be something here about getting a new iPod and digital camera on average every year (and phone for that matter).
