Participate in conversations as an introvert

Just introduce yourself.
Give a brief introduction of yourself. It’s the beginning of any conversation with a stranger, and often the biggest obstacle to overcome.

Passively participate.
Just ask incredibly open-ended and personal questions to people and act like a mirror to them.

Think out loud.
Introverts think their thoughts alone and in peace but that does not mean those thoughts cannot be mused on. Try starting a conversation by using those thoughts as a conversation starter.
