It was a great review for the DAT in college, and the national boards in dental school. Finding and becoming a mentor is something successful people do throughout life. If you hope to succeed in any endeavor, you need to develop rock solid confidence. Remember that a confident person has a very positive self-image, and is someone who prepares for the challenges of life, be they final examinations, getting into graduate school, or starting a career. Do not underestimate the power of confidence.
Confident people respect others, but also command respect from others.
Confidence is a very attractive quality to employers, patients, other professionals, and to peers in social situations. If you are not confident, you will never be able to achieve high goals, and will resent others that do. One word of caution, not everyone admires or likes a confident person. Weak and insecure people will often be hostile to you because your strength forces them to see their own weakness. As soon as you run into these types of people, do your best to avoid them.
