You sold my car?!!!
I understand though- I've done the same thing. The whole "Fiscal Responsibility" thing. It sucks, but as a result I have no credit card debt at all, and we have a savings account now. There's a certain satisfaction knowing that fact. BUT- its a slow process. It takes a LONG time (at least on my salary) to build serious wealth. Its super, super easy to spend it.
The best spending rule I've come up with is this- I get all ready to buy something, then I wait a week. This has prevented 3 major senseless purchases so far.
