I am thinking Dave (and Jack) recommend not only frugality, but finding a way to increase your income... even if it is just an extra part-time job for awhile... Lvschant
Do anything that you can do to increase your income, and particularly try to find things that leverage your time.
One example is selling stuff on eBay. You spend a litle time digging up stuff from yardsales, and a little time putting it up on action. Then it's up for a solid week, encouraging people to send you money. You can do that twenty times in a week, and not use up the whole week doing it. That's the leverage.
A hundred bucks is not a lot of money, until you compare it to zero bucks. Increase your income by a hundred bucks a week, and that's $400.00 a month. It'll really help with the bills.
And the longer you do it, the better.
