"The stresses & worries are like that glass of water. Think about them for a while & nothing happens. Think about them a bit longer & they begin to hurt. And if you think about all day long, you will feel paralyzed - incapable of doing anything."
All true, being introverted isn't bad. It's just how people view them that's bad. It can be annoying when people don't see them for who they are. They give up and say,"ahh they're too quiet so sooo ill just leave."
