It's also a mistake to work hard every day and when payday comes along, you have no money to show for all the work you've just put in. That's what happens when you are in debt and every cent goes towards bills.
It's so much nicer to have actual money in your pocket from all the hard work you've done when you aren't in debt. Then you'll be able to save money, increase your wealth.
You can't do that if you are in debt. Keep a hold of as much cash as possible, it's the only way you will be wealthy and change your life for the better.
