Wow! Must have been affirming to have your performance review go so well!
As far as hoping to increase verbal participation in meetings, there's no guarantee we'll always say the right thing at the right time.
However, chances are you will have the right message or suggestion with the right timing. Why do I think so? You do so here. Repeatedly.
I am super careful about talking when I am hypomanic; otherwise, I trust myself.
You will build more confidence in yourself via increasing your verbal participation, even just a little.
Congrats on the positive performance review!
