Follow Your Heart runs on the theme of love. The author attempts to touch on various forms of love—namely, romantic love, filial love, love between siblings, love for children, love for your country, love for music, love for cricket, love for money, love for friends, love for flora and fauna, and self-love, which she thinks is most important. If you love yourself, everything else falls into place. The author believes in following her heart to stay happy. Love is the loveliest emotion in the world. The book should, therefore, appeal to both the young and the old.
