The article recommends that businesses be "neutral" with respect to suppliers (don't depend on one), employees (don't depend on a star) and customers (don't depend on one). Spread your business among multiple suppliers, cultivate a pool of people that you can hire if someone leaves, don't allow a single customer to represent more than 15% of revenue. To that I would add, as an individual, don't depend on a single employer. Ideally be in business for yourself and structure as above. Otherwise, if you're an employee, have at least one more source of income that will pay a good portion of your expenses. Do the odd freelance/consulting job. Be able to walk away from any source of income without immediate disaster.
