Cite the record relentlessly — appellate courts decide on the record, not new arguments
Use argumentative headings that state conclusions
Distinguish unfavorable authority rather than ignoring it
Address harmless error proactively for each issue
Never misrepresent the record — appellate judges check citations
Verify all authority or mark [VERIFY]
