"My mantra is: put your brain into gear and if you can add to what's on the screen then do it, otherwise shut up"

In essence, Richie Benaud is encouraging people to think critically prior to speaking or contributing to a conversation. He emphasizes the value of adding something important to a discussion, rather than just talking for the sake of it. Benaud's "mantra" of putting one's brain into gear highlights the significance of actively appealing and thinking about ideas prior to verbalizing them. This quote likewise indicates that it's much better to stay quiet if one does not have anything important or helpful to include, rather than wasting time and energy on worthless talk. Ultimately, Benaud advocates for thoughtful discussion instead of blindly participating in casual chatter.
