I realize introverts don't work that way, I know, I am one. But I've had some of the most brilliant ideas come through purely on a discussion nay sometimes an emotionally charged argument.

Important decisions are almost never 2+2=4, if they were, they wouldn't be important and yes you wouldn't need a meeting (like I admitted, there's definitely a lot of unimportant meetings).

But important decisions are almost always an exercise in coaxing, cajoling and persuasion, which is just extremely low fidelity on paper.

Most engineers will look at their team leads and say "I don't believe in this strategy on paper", and all their team leads can say is "I was at the meeting. You had to be there"

I'm an introvert, too. I have no troubles participating in, or leading, or even fighting in group activities. Does it exhaust me? Yes, it does. I literally feel physical pain if I have to stay in company for more than maybe an hour. But value is created through interaction, not some process, paper stacks, or a lone wolf hiding in the closet, so I learned a long time ago how to communicate effectively, give and take feedback, organize tight meetings, and facilitate decision making.

I'm actually a bit tired of introverts hiding behind their disposition. You can do something about it, and it's more than complaining.

EDIT: Sorry, that was more rantish than I wanted. But I'll leave it here anyway.
