Sarah Ban Breathnach rose to success after publishing her landmark book “Simple Abundance: A Daybook of Comfort and Joy” in 1995. After a resounding endorsement from Oprah Winfrey, she found her book atop the bestseller list for two years, going on to sell more than 7 million copies.
“Simple Abundance” popularized the concept of the “authentic self” and the practice of keeping a gratitude journal—two key ideas that are still touted in the self-help space today.
