“Money is a great servant but a bad master.”
“It is with our passions, as it is with fire and water, they are good servants but bad masters.”
“You gave too much rein to your imagination. Imagination is a good servant, and a bad master. The simplest explanation is always the most likely.”
“If money be not thy servant, it will be thy master. The covetous man cannot so properly be said to possess wealth, as that may be said to possess him.”
“Fire and fear, good servants, bad lords.”
