“Growth is not merely a harmonious increase in size, but a transformation. Man is a sculptor of himself, urged by a mysterious inner force to the attainment of an ideal determined form. Growth may be defined as a seeking after perfection given by an impulse of life.” -Dr. Maria Montessori, To Educate the Human Potential
