millionaire

This morning, I watched Oprah Winfrey and the topic was how to be a milionaire. For those interested, the principle is to pay yourself first. (another word for savings) Then to cut down by half the total amount spent on luxurious expenses. Of course, there must be investment too. So if I follow this advice, I am on my way to be a millionaire.
Trying to think what my luxurious expenses are. What is yours?
