What does it mean to be customer obsessed or achieve customer obsession?

Customer obsession is a state of mind. To embody a Customer Obsessed state of mind, one must consider the customer they are obsessed with in all things. For example, when at the grocery store you see an advertisement from a competitor of your customer, a customer-obsessed state of mind will naturally conceive of methods that a customer might employ, out-competing the viewed advertisement. When going to sleep, the customer and their needs are the last thoughts that drift from your mind as you fall asleep. When waking up, the customer should be the first thought to naturally occur as you begin to consider your activities. When eating your lunch, you should imagine what your customer is eating for their lunch.

When your customer is on your mind every waking moment, you've begun to walk the path of being customer obsessed. Once you've begun dreaming of your customer, then you will then have achieved true customer obsession.
