Love is the greatest thing in the world. This quote is like Gatsby¡¯s life. Since Gatsby devoted his whole life to his lifelong lover, Daisy, Fitzgerald maybe used this line as a quote of this novel. Gatsby worked and bought an enormous house for Daisy. He held parties to meet her and even died for her. Maybe that¡¯s why Gatsby is ¡°Great Gatsby¡± because love is the greatest thing in the world.
