I am an introvert and I believe my shy nature might be holding me back at work.

I enjoy keeping to myself and rarely contributing in team meetings. It's not because I am a bad team player (I am actually a good team player), but because there is this mental battle I have to fight each time I'm in the company of others like my supervisors, managers, colleagues, etc.

It really hinders my works and during meetings and brainstorming sessions, even though I have good points to share, I never get to do it. It may not have visible effects now, but it might later be my Achilles feet.

I don't know if it's same with other people, but does anyone care to suggest how to tackle this?
