1) Clip coupons. It may sound cheesy, but using coupons on food, especially, can be beneficial. The thing is you would have to open minded to trying new products or buying more inorder to see the savings and discounts.
2) Set aside money every paycheck. This can be $5.00 to start. Then $10.00. Watch the difference it makes after six months.
3) If you have to, withdraw money you need to spend and leave your credit or debit card at home. This will force you to use what you have and be frugal about what you buy.
4) Stay committed to your goal and finances.
