Keys skill discussion

I thought the things that went well were that I managed to speak and I agreed with other people by using different words.
Also I answered questions John asked and i was using eye contact to show I was listening.
I also sat with open body language.
And lastly I nodded to show I was listening to other peoples views on the discussion.

How could it have been better.
I could have filled in my sheet and used that for research, and I didn't ask any questions.

I think I should prepare a question or two for future discussions and I should have time to go over of what i have to do.
