When Charles Dickens was 12 years old, he went to work in a shoe polish factory while his father was relegated to debtor’s prison. The experience stirred his lifelong zeal to expose the social and economic plights of the lower class in 19th-century London. Arguably the most popular writer of his day, Dickens published 15 novels before he died, including “Oliver Twist,” “David Copperfield,” and “Great Expectations.” His last completed novel, 1865’s “Our Mutual Friend,” contains a quote that speaks to anyone who has questioned their purpose. Helping others — especially those in need — is the path toward a fulfilled life.
