I finally spoke up! Any other introverted women feel like this at work?

At work the other day, in a meeting in front of almost 50 different community groups, I totally killed it. I stood up for my not for profit organization against 2 adult bullies who had been putting my organization down for months. I hate confrontation, and honestly it took everything out of me to stand there and call them out on it while 50 people watched, but I felt so good after!

It wasn't just the social anxiety of speaking in front of a group, I'm a person that needs to prepare ahead of time before speaking like this, so this was especially difficult for me.

Sitting in my car after the meeting, unclenching my jaw, I got thinking about how much I've grown in the last few years. Looking back I think being an introvert really held me back and I didn't know it. I'm thinking of maybe starting a website to help other women who are maybe a little introverted, but want to become leaders or managers. Does anyone relate to this? Would a website like this be helpful? If it could help your career move faster, would any women pay for something like this? (Not trying to be greedy, just trying to see how serious interest might be)

Thanks for your thoughts!
