Joining a mentoring program is a very powerful tool that can help you reach your potential because of the training and empowerment it provides. Mentoring is also one of the most effective ways for you to advance in your career because your skills are developed and your performance is monitored.
In short, mentoring enables you to be the person you really want to be.
A mentor will help a mentee believe in his or her capabilities as a person. Because of this, the self-confidence of the mentee will be improved and they will be more apt to accept more challenges in the future. The mentor would also enable the mentee to explore new ideas so that you can achieve a higher level of self-assurance in yourself and explore even greater highs of success. The mentoring program will be an opportunity for you to take a deeper look at yourself, your goals, your personality, and your life. This will enable you to know which the right path you should take in life is.
