Interested in reading about others' mentoring experiences? Check out The Soloist, by Steven Lopez, or Same Kind of Different As Me, by Ron Hall and Denver Moore. The Soloist is an account of how Mr. Lopez, a Los Angeles "Time" journalist befriends and informally mentors a homeless man. The other book is a mentor's and mentee's description of how their relationship developed over time.
Both books describe many experiences similar to those mentors and mentees with Trusted Mentors. The rewards and challenges of mentoring are well described.
