Behaving, thinking and sounding as neutral and involved as your coaches

Through my accesses and the calls I really have to say I want to look, sound and behave as collected and non-judgmental as your Coaches. How do I do that? I see that I show a lot of emotion and interaction when I am in an exchange and I don’t feel it is as helpful, professional or becoming than sounding under control, present but not necessarily expressing my opinions or viewpoints. Guide me through this please.
