Human or general needs can be satisfied through society; for satisfaction of unique needs you must do some seeking. A friend and a friendly service, or even an individual's service, society cannot procure you. And yet you will every moment be in need of such a service, and on the slightest occasions require somebody who is helpful to you. Therefore do not rely on society, but see to it that you have the wherewithal to - purchase the fulfilment of your wishes.
