Five simple things to remember in order to have a more effective meeting:

1. Respect people’s time. Don’t be late. Finish on time.
2. Prepare before coming to the meeting
3. Understand the goal and purpose of the meeting and contribute to the overall goal of the meeting
4. Make sure you take notes even if you have the most brilliant memory. It will give people the impression that you listen to them carefully and you will refer to your notes later on.

Speak loud enough that everyone can hear you, slow enough that people catch up with what you are talking about, and precise enough so you don’t waste their time.
