Vinh Quang Giang on Instagram: "This is the secret to building rapport FAST. If you want to learn how to build rapport with people instantly, it starts by learning how to match and mirror their vocal foundations. This means their rate of speech, their volume, their pitch variety and their tonality. If they are slightly sad, and speaking with low volume, meet them there. Once you meet them where they're at, then you take them to where you want to be."
