Firstly, appearance and demeanor play an extremely vital role during a first meeting. People tend to make quick judgments about someone's personality and attitude based on their attire, posture, and facial expressions. As an example, cartoonist Robert Grossman was adept at capturing the physical appearance and character traits of celebrities with simple brushstrokes. He pointed out that personality can be unmistakably revealed through body language: Clinton's half-smile suggests boyish charm, elder Bush's shoulder angle depicts his awkwardness, and Reagan's gaze reveals his charisma. Therefore, maintaining good posture, decent attire, and a confident smile can immediately generate a positive impression on others.
