Instead of eating out once a week, cut it down to once a month and make it a real reward for having lived within your budget for the preceding month. With your cooking, prepare more of your meals from scratch instead of serving processed, pre-cooked or hear and serve meals. Use paper towels or do without napkins. Use bread wrappers and save those place containers - just wash and use them for keeping leftovers. Use washable cloth handkerchiefs instead of expensive facial tissue.
Clothing is another area in which most people can save.
Learn to sew on buttons, repair ripped seams, and sew on patches. Never throw anything away - if something becomes outgrown or no longer wanted, save it for a garage sale or trade for something you can use at a second hand store. Learn all you can about auto upkeep and minor repairs. Save and sell all materials that can be recycled such as aluminum, bottles and paper. Don't splurge on gifts - either at Christmas or on birthdays.
