If I may be so bold as to add a couple:
Grin and Bear It - Sometimes despite all your informed, documented reasons why a certain course of action is unwise if not downright stupid, people who make more money than you do will insist upon taking it. Sometimes you have to salute, say "Aye-aye Cap'n Bligh" and do what is requested. (Yes, that has limits but I think they're obvious).
Which leads to the corollary: Thou Shalt Keep a Mop and Bucket Handy. When the above happens be ready to clean up the mess when the train wreck hits.
And can I give a hearty "AMEN" to no. 6? I'm smack in the middle of one of these now with overtones of the two above.
It ain't pretty.
Just my $0.02 from over here in the cheap seats of the peanut gallery - please adjust for inflation and/or your local currency.
