You work too hard to get to the end of your life and have nothing to show for it. When your money is tied up in monthly debt payments, you’re working hard to make everyone else rich BUT you.
 
And along with that, your cars, trucks, boats, motorcycles, and other vehicles should not have a total value that exceeds half your annual income. Why? You don’t want too much of your wealth tied up in things that depreciate (go down in value). And cars, trucks, and things with motors depreciate big time.
