This article provides readers with five lessons the author has learned over the years as a mentor teacher to several preservice teachers: (1) Build confidence; (2) Be patient, flexible, and honest; (3) Listen and learn; (4) Be ready for extra work; and (5) Embrace the experience. Included in her reflective thoughts are comments from two of her former proteges obtained through conversations and surveys completed during their time together. The author offers her thoughts and those of her new colleagues as authentic viewpoints one may find useful for his or her own mentoring practice.
