If you want to save your sorry a$$, PAY ATTENTION to the briefing!! I have been a maintenance engineer for 13 years, and have flown all over the place, usually in the same types (DHC-8, BAe 146, 737). It pays to listen. In an ongoing attempt to increase your chance of survival in an incident, the briefing is, from time to time, modified. If things have changed since the last time you flew, HOW WOULD YOU KNOW?? I cannot stress the importance of this strongly enough.
Besides...its only polite to listen when someone is talking to you. It sends my wife into fits when she is talking to me and I have my nose stuck in a book!!
