10 observations about Introverts/Extroverts:

1. The notion that "We need to become Extroverts to be successful" should go away. The world also needs thinkers and thinkers are generally introverts.
2. Newton, Albert Einstein, Madame Curie, Rosa Parks, Steve Wozniak, etc -some of the famous introverts.
3. One of the notions that we should know as many people as we can is also flawed. We only have limited time on the planet and we can substitute some needs of the people by machine or apps. e.g. You move to a new city and often, you will need a bike to go somewhere. Here, You can rent a bike rather than becoming friends with someone who has a bike.
4. Open workplaces may make you connected with other people but they don't help you foster creativity. A human mind should be free from distractions to create something.
5. People should respect introverts. Some people just like to read a book rather than traveling.
6. Society needs to accept that being in solitude is not a negative situation.
7. Not everyone should do public speaking or learn to do it.
