It reinforces the importance of working to a budget and monitoring where your money is going. If you have no idea what you're spending money on, chances are you're wasting a lot of it.
Even if you aren't short of money at the moment, it's worth taking stock every so often. Look back at recent bank statements and check where you're spending money. You might be surprised at how much is leaking away.
Some financial advisers describe this as the "leaky bucket" effect - it doesn't matter how much money you're putting in your bucket each week or month if there's a hole in the bottom that's sending a decent chunk of it to local cafes or pubs on a Friday night.
If you're finding that you're having trouble keeping everyone accountable to your spending plan then seek someone to help you, pointing towards your financial goals - there is help and techniques to help if you ask.
If you are able to be a bit more conscious of where your money goes, it's likely you will save more than you expect.
