Have you ever signed up for a rewards program? While they vary, rewards programs typically include incentives for doing a specific behavior. If they want you to buy more and more often, you may earn bonus points when you make a purchase and then have a limited time frame to redeem them. That way, you come back quickly. Or, you get a discount, a rebate, a coupon, all intended to keep you returning and doing that specific behavior over and over again. These systems encourage and reward behaviors, which create habits that can last a lifetime.
