Dr. Yalom's latest book, The Gift of Therapy: An Open Letter to a New Generation of Therapists and Their Patients, is a compilation of psychotherapeutic wisdom. Yalom begins by acknowledging his indebtedness to his early professional influences. He mentions the work of Karen Horney, Erich Fromm, Carl Rogers, and D. W. Winnicott as having shaped his professional development. He sites additional resources he has integrated into his practice, clinical writing, relationships with family and colleagues, teaching, and his deeply felt relationships with his patients as well as poetry, philosophy, and literature.
