Yes you are right, I will tell you what to leave when your are going to a meeting. There are many things that should not be brought to a meeting or else it will not be a meeting it will be a waste of time.
- Leave the Job hierarchy outside the meeting room. Everyone should have an equal voice and opinion. If you are a CEO and would like to make a decision simply send an email to everyone and do not hold a meeting to reject every body's opinion to make them conclude that your decision is the optimum right.
- Leave Your Ego outside the meeting room. Your meeting target should not be to adopt as high percentage of your ideas as possible. The whole set of people who attended a meeting will share the credit (and of course the debt ;-) ) of what decisions were reached.
- Unless the meeting is with your boss who belongs to category 1 please leave your need to sleep outside the meeting room. I know how hard is it to do that in today's world of business ;-).
