Launder clothes according to instructions. Drying on a line instead of the dryer will extend the life of your clothes. Take snacks with you. Shop toiletries carefully - some stores discount these. Try to develop interest in activities that don't require spending such as walking.
Major newspapers list free or minimal charge entertainment activities each weekend.
Do your own pet grooming. Use an inexpensive shampoo and add two tablespoons of baking soda to the water for a soft coat. Cancel subscriptions to magazines and book clubs. Use the public library instead. Then determine how much money you need to make to achieve that lifestyle.
