"Influence" tells the story of influence as an art. It is invisible, but it is everywhere, present in every moment of human relationships. The first impression brings about the primacy effect. It only takes 30 seconds for a stranger to have an initial impression of the other person when they meet. The degree of personal charisma determines the degree of influence. More than 70% of the world's richest people accumulate wealth mainly through connections. Managing and maintaining connections is an important guarantee for maintaining influence.
