A trigger is anything that makes you want to shop. Keep a journal with you for at least a week, and whenever you feel the urge to shop, write down whatever you feel brought the idea into your mind. It may be a particular environment, friend, advertisement, or feeling (like anger, shame, or boredom). Knowing your triggers is extremely helpful because you can avoid the things that make you want to shop as you are learning to decrease your habit.

This way you can keep shopping occasionally, but stand to avoid some of the larger financial issues that can come with the habit.  When shopping, carry as much money with you as you know you can get away with spending. Leave your credit cards at home to avoid temptation to go over your limit. You can also try making an inventory of the things you own and a wishlist of the extras that you really want. Looking at your list will help keep you grounded and able to recognize when you're about to purchase something you already have a lot of or something you don't want as badly as other items that you'll surely be tempted to purchase. Wait at least 20 minutes before making a purchase. Don't be sure that you must buy something; instead, spend time thinking about why you should or...
