I spend too much money. How can I get on the path to a frugal lifestyle?
For many folks these days, not having a credit card is just not practical. Personally, I do quite a bit of shopping online for things not available locally. Cash is not an option in these cases and I don't want to give out my debit card number. So, a strategy is this: use a credit card for a purchase. Then immediately, or within a couple days, pay the credit card with that amount. Sounds simple but it takes a little effort to do it. This strategy gives you the convenience of a credit card and decreases the interest enormously.
