X. You shall insure your ability to make money

Going through the retirement-planning process can become moot if catastrophe interrupts your ability to make, and therefore save, money.
"Insure your life and your ability to earn a living through disability," Kuhn says.
The amount you'll pay for insurance will be based on your age, occupation and income, but you can buy as much or as little insurance as your budget will allow.
"If you have a budget, you'll know how much you can set aside. Whatever that buys you, it's better than not having anything at all," says Kuhn.
