In a better world it would be something like "Always be honest", "Treat your employees well, they're the source of your wealth", "Take resonsibility for your mistakes and learn from them" or some such.
In reality I think it is:
Know the limits of your bullshitting skills. Know how far they can take you - and know when it's time to stop. Whether with customers, coworkers, or superiors. Don't play your hand too early, but know when to quit.
Don't compromise when you don't need to, but don't be a bastard, either.
If the guy/girl working across from you making a third of what you're making could have your job, they'd throw you under the bus in 2 nanoseconds flat. Don't give them an opportunity.
