Your career path might not be as smooth as you had imagined or planned. Sometimes you will face challenges and you will be on the brink of quitting. Without any motivation, you will decide to quit, take a break, or forfeit your success. Mentors come with encouragement that can keep you going. Oprah Winfrey, an inspirational entrepreneur, defined a mentor as "someone that allows you to see the hope inside yourself." A mentor's principal concern in your engagement is to ensure that you achieve your goals and, when you are almost caving in, they are there to get you back up. Therefore, mentors will hardly let you stop, and, when you are facing the most challenging of obstacles, they will encourage you to keep going, and give guidance on how you should do that.
