Silence is Golden?

I do believe in teamwork
But what if any of them is not participative?
I don't know the next move
I care about about the marks and relationship

But someone tell me what can I do to make the person speak

Silence isn't always an useful way to communicate
How could we know what's on your mind if you don't talk your mind?
I don't mind an answer with mistakes or a sentence with broken language

We, as a team, need IDEAS
More and More IDEAS

Remember, Creativity brings Innovations
And that's what we're lacking.
