What’s sage professional advice you’ve either received or given throughout your career?

Don't declare bankruptcy and claim everyone who is successful does it; don't grab women by the pussies, don't lie on average 26 times per day; don't build walls around people you might be afraid of to gain a political advantage; don't spend most of the day watching TV and every weekend playing golf at taxpayer expense while claiming to work. And, if you have a daughter, don't treat her like your personal sex object.
