A leader will explain to all attendees WHY they are together, WHAT the goal is and, WHEN they are finished.
Take a pen & paper. Take it down. Take responsibility.
If you need to setup your laptop or load your presentation – do it BEFORE the meeting starts.
Only invite essential people to your meeting. Everyone else will thank you.
A quick confirmation saves everyone time.
Bring people together to engage and discuss. Do not bring people together to simply share.
