Never, in peace or war, commit your virtue or your happiness to the future. Happy work is best done by the man who takes his long-term plans somewhat lightly and works from moment to moment 'as to the Lord.' It is only our daily bread that we are encouraged to ask for. The present is the only time in which any duty can be done or any grace received.
C. S. LewisThere is one bit of advice given us by the ancient Greeks, and by the Jews in the Old Testament, and by the great Christian teachers of the Middle Ages, which the modern economic system has completely disobeyed. All these people told us not to lend money at interest; and lending money at interest - what we call investment - is the basis of our whole system.
