A great man or woman is any man or woman who outperforms his or her counterparts in a particular field, sphere, dispensation or a given period of time i.e. extraordinariness or uncommonness is nothing but a sign of greatness. But, mind you nobody has ever become truly great by his or her own strenght, intelligence, wealth or hardwork. Yes! it takes only God's grace to achieve true greatness in anything in life (Psalms 75 : 6).
