Before you get to the next meeting, learn about what it is about.
Take 5 minutes and think about what is being asked of you.
What questions will you ask?
What questions will be asked to you?
What materials would prove useful to bring?
What will you be required to do?
How will you present yourself?
The goal of any meeting is to accomplish a particular objective and not to have the meeting. The need for the meeting is greater than what can be accomplished via an email.
So before you get there, show up and be ready, only then will you be able to start.
