Are you a beacon for your colleagues? Where does your light shine to guide them?
Take a look at your speech. Do you say: “Please avoid mistakes“ ?or do you ask: “Which opportunities do you see?“
The first question will shift their attention to sources of error and less to development. The second question will bring about development and people’s potentials.
Both possibilities are true, there is no judgment. But please ask yourself what exactly you want.
It is possible to focus the attention of your colleagues on certain objects, attitudes or point of views. Each of your questions is an invitation, and has an effect.
