In 2015, Gilbert published Big Magic: Creative Living Beyond Fear, a self-help book that provides instructions on how to live a life as creative as hers. The book is broken down into six sections: Courage, Enchantment, Permission, Persistence, Trust, and Divinity. Advice in Big Magic focuses on overcoming self-doubt, avoiding perfectionism, and agenda setting, among other topics. Gilbert continued the work started in Big Magic with her Magic Lessons podcast in which she interviews famous creatives including Brene Brown and Sarah Jones.
In 2015, Gilbert and several other authors including Cheryl Strayed participated in fundraising efforts for Syrian refugees which raised over $1 million in 31 hours. In 2016, Gilbert shared a video of herself singing a karaoke version of Bonnie Tyler's “Total Eclipse of the Heart” to raise money for BlinkNow Foundation, an organization inspired in part by Eat, Pray, Love.
In a 2015 article for The New York Times titled "Confessions of a Seduction Addict," Gilbert wrote that she "careened from one intimate entanglement to the next—dozens of them—without so much as a day off between romances." She acknowledged, "Seduction was never a casual sport for me; it was more like a heist, adrenalizing and urgent. I would plan the heist for months, scouting out the target, looking for unguarded entries. Then I would break into his deepest vault, steal all his emotional currency and spend it on myself." She realised that, "I might indeed win the man eventually. But over time (and it wouldn’t take long), his unquenchable infatuation for me would fade, as his attention returned to everyday matters. This always left me feeling abandoned and invisible; love that could be quenched was not nearly enough love for me".
