12. Plan out Leftovers

If you don’t have time to cook every day of the week, that shouldn’t be a problem unless you don’t plan accordingly. You’ll be spending more money by eating out all the time, so all that saving will account to nothing. 

Consider making bigger meals so you have some leftovers to enjoy, either at work or for breakfast. Don’t just assume you’re going to have enough food for several days. The more aware you are of your leftovers, the better.
