I always use my clients' products. This is not toady-ism, but elementary good manners.
The best ideas come as jokes. Make your thinking as funny as possible.
I know of a brewer who sells more of his beer to the people who never see his advertising than to the people who see it every week. Bad advertising can unsell a product.
My motto has always been: Only first class business and that in a first class way
What you learn is more important than what you earn.
Never use jargon words like 'reconceptualize', 'demassification', 'attitudinally', 'judgmentally'. They are hallmarks of a pretentious ass.
