my new year resolution

My new year resolution.
1) Save money.
Food - $400.-
Restaurant $100.-
Baby expense - $60.-
Gas $160.-
Others $200.-
Put on the saving account $400.-

I recently went back to Japan. I found lots of magazines featuring how to save on household expenses, such as food, energy, and so on. Some expert housewives spend only about $100 a month.- but their eating doesn't look so poor. Using cooking technique and knowledge, You may spend much less on everyday food. My current is about $500, I want it to be within $400.
