Mentors take an active interest in developing an entrepreneur's career by providing guidance based on their own experiences. They help entrepreneurs avoid common mistakes. Coaches focus on solving specific short-term issues, while mentors provide broader advice over the long-term. The entrepreneur must maintain the relationship by following up and keeping the mentor engaged. As a business grows, mentoring shifts from business matters to developing the entrepreneur as a leader. Mentors contribute out of care for others and passion for the field.
