Here's the thing. I used to be an extreme introvert by all standards, and preferred being alone. Social interaction was extremely tiring. Now I'm comfortable both with people and alone. However, the real question is why it was tiring. It was tiring because I wasn't comfortable, it wasn't second nature. It took extra effort, just like all other the things we do that we aren't good at doing. When it eventually became easier and took less effort, it naturally also became less tiring. I wish we could just stop with the stupid binary introvert/extrovert terminology. It's on the same pseudo-scientific level as saying people are left-brained or right-brained, people aren't that binary or simple. If I, 10 years ago, had just said to myself "I'm an introvert, social interactions aren't my thing and they make me tired" I'd likely be significantly less happy than I'm now.
