If you choose to
stick to your new grocery
shopping when you start working again — or if you only allow yourself to visit the fancy store at the end of the month if you still have money in your grocery budget — you'll be creating an important new
habit that will help you long term.
You could just be in the
habit of buying the wrong food every time you go
shopping simply because you don't have a
shopping list written in advance where you know exactly what you should be buying and
sticking to that list rather than buying whatever meets your fancy.
