When anyone asks "How is it going", I just say "Good, how are you doing".
There are always awkward pauses. I am skeptical about speaking anything without preparation in advance. Want to communicate well with others (not only in office but outside office too) that may lead to long term friendship with at least one or two people. Any coaching you recommend for extreme introverts to build this skill?
I recommend these other discussions:
I consider myself an introvert and was incredibly shy up until high-school. What's important to remember about being an introvert is that your strength is building up a small amount of incredibly deep relationships. Make just 1 great professional friend, understand what worked, and then "export" that model to everyone else to make all the friends. 😊
To start, each morning, you can brainstorm 2-3 things that you can talk about so you aren't caught completely off guard. These things don't have to be extravagant. They can be as simple as something you ate recently, a show you started watching, or a new interest you started to pick up. Over time, you'll be able to come up with things organically.
The goal is to give the other person something, anything, that they might be able to elaborate on, either through a shared experience, or just because they are curious about what you are talking about.
You should also turn the tables around and ask them how they are doing, and be curious and open-minded about other peoples' interests.
