Richard Boyatzis, professor at Case Western Reserve University, says that every professional can benefit from having a coach — and serving as one for someone else. He says that a coaching relationship moves beyond mentoring or sponsoring in that it focuses on long-term values and aspirations. The best coaches encourage a positive mindset and ask probing questions to help people make the best choices, not only in their careers but also in their personal lives. Boyatzis is coauthor of the HBR article "Coaching for Change."
