I want to list ten controlling principles for the outward expression of simplicity. They should not be viewed as laws but as one attempt to flesh out the meaning of simplicity into twentieth-century life. First, buy things for their usefulness rather than their status. Second, reject anything that is producing an addiction in you. Third, develop a habit of giving things away. De-accumulate. Fourth, refuse to be propagandised by the custodians of modern gadgetry. Fifth, learn to enjoy things without owning them. Sixth, develop a deeper appreciation for the creation. Seventh, look with a healthy scepticism at all 'buy now, pay later' schemes. Eighth, obey Jesus' injunction about plain, honest speech. Ninth, reject anything that will breed the oppression of others. Tenth, shun whatever would distract you from your main goal.
Richard J Foster, 1979
