Quote I like

"Rarely is it effective advocacy to try to convince the judges that the case law compels them to rule in one's favor. For if that were so, the case probably would not have have gotten to the appellate stage. The most effective method of arguing a case is to identify the purpose behind the relevant legal principle and then show how that purpose would be furthered by a decision in favor of [your] position." How Judges Think, Richard A. Posner
