I'm not saying that it's a bad idea to ask questions, but I find I'm always learning more when I'm listening as opposed to talking.
It's a silly phrase but an easy one to remember and its served me well in the recent past. And it's not just about learning more when you listen it's about our ability to be more compassionate and helpful to others when we listen.
I used to love the TV show "fraiser" who's catchphrase was "I'm listening"
It's not a bad place to start.
