A role model is a person who inspires and encourages us to strive for greatness, live to our fullest potential and see the best in ourselves. A role model is someone we admire and someone we aspire to be like. We learn through them, through their commitment to excellence and through their ability to make us realize our own personal growth. We look to them for advice and guidance.

A role model can be anybody: a parent, a sibling, a friend but some of our most influential and life-changing role models areteachers.
