Challenge yourself to find new ideas.
Keep an open mind.
Plan on listening 80% and speaking 20%.
Respect the host, as tomorrow it you may be you.

One person talks at a time. Avoid interruptions and side conversations.
Signal the host if you want to make a counter point.
Turn off walkie-talkies and silence mobile phones.
