Might I add one more rule to the list?
1. Do not try to stuff your 95 lb "carry on" bag into an overhead bin. This will usually require you to have to remove someone else's normal sized carry on from that same bin, depositing it elsewhere. Which can be confusing for the owner of the normal-sized bag. And should your 95 lb. carry on bag fall out of the overhead bin, say during some moderate turbulence when the aircraft is flying at 600 mph rocking 30 degrees from side to side, and it hits me on the head, I will hunt you down. And it won't be pretty.
