You don’t have to be the loudest one in the room to be the one people check with before deciding.

There are two kinds of influence in any group, and only one of them is audible. The loud one fills the room and moves on. The quieter one gets consulted in the corridor, before the decision is actually made, because people have learned that your read is usually sound. That second kind is built slowly out of being right and being discreet.

Keep doing the unglamorous part: know the details, say less than you could, and never repeat what somebody told you privately. When you do speak in the room, make it one clear sentence rather than three.
