Ask open ended questions
by introvertsuccess
Although introverts can be very talkative at times, especially when talking about things we are passionate about, it can often be the case that we don’t really have anything to contribute in a conversation.
One of the best things you can do is encourage the other person to speak by asking open ended questions.
“What…?”
“Why…?”
“How…?”
Avoid asking questions that can be answered with yes or no answers.

I often make the mistake of asking those yes or no’s, such as “Are you…?”
But my favorite after hearing an opinion is to throw back, “Why do you think that?”
