Anna Robertson Brown Lindsay (1864–1948) was the first woman to earn a doctorate at the University of Pennsylvania. She wrote a number of books on theological topics, most of which were published in the early-1900s. Anna Robertson Brown Lindsay was the daughter of a Presbyterian minister and the first woman to graduate with a Ph.D in English from the University of Pennsylvania.
Her certainty of God was at the center of her tenets on restructuring one's life to dismiss the unimportant, irrelevant, and nonessential aspects of life. One line in her book, "What is Worth While" provided enough insight to provide a lifetime of reflection. She writes, "We may drop worry...Every moment of worry weakens the soul for its daily combat. Worry is spiritual near-sightedness; a fumbling way of looking at little things, and of magnifying their value. Seen in their true relations, there is no experience of life over which one has a right to worry. God gives us always strength enough, and sense enough, for everything he wants us to do."
