Why do i never learn?

I spent around 3 years paying for splurges I incurred from 5 credit cards (HSBC, Metrobank, Citibank, Unionbank, Bankard) .. the most rash one was a trip to Boracay while the others where a lot of little things that i've forgotten.. mostly coffee and basically buying stuff that I could not pay for at once. I think my pc is part of the list.

And after finally paying them all off around 5 months ago, I've brought the ghost of debt back to life by incurring 80k of debt one just one credit card. How sad is that?? I did major splurging at the gym..and also got myself into an investment that i was supposedly ready for but i used the money on the gym stuff instead (membership, personal trainor, nutritionist, massages).

Knock knock knock.. earth to myself! Why do i never learn.

Based on my calculations.. I'll be able to clear my card on March 2009. Great, just great!

I should put some kind of validation before handing over my card to the cashier
1) Are you sure you want to buy that?
Yes-->
2) Based on the money in your ATM, you cannot afford to pay that
Proceed with purchase -->
3) Warning: Do not continue with the purchase
Proceed with purchase -->
4) Error: cannot continue with the purchase. Not enough money.

hehehe.. siguro naman natauhan na ako by then!
