I know you have heard this before, but make your bed every day!
Make sure you budget each week for food and shop for it. Stop ordering out or eating fast food. Use this one day a week to cheat.
Clean your house every morning or night. Even if it's just one thing. Start there. Wash the dishes, vacuum, throw out or donate some things that you don't use and show your kids how to do this as well.
Drink 8 glasses of water a day.
Exercise.
Keep a list of your shopping expenses every week. At the end of the month see how you spend on things you don't need.
