A mentor is a very valuable person you can have in your life. Many people don't see education as a life-long process but it really is. If you're not learning, you're not growing, and after receiving a formal education, a lot of people think that they're set in life and won't need another teacher to show them the way. But a mentor does more than what a teacher would do. A mentor guides you, advises you, and supports you in not only your personal life, but also in your career. Think of a mentor as a friend who've done what you've done and can show you how to do it better than what you're doing now.
