The author is reflecting on the upcoming end-of-year review and encourages readers to take a structured approach to their marketing audits, which should include identifying what worked, what didn't work, and what they want to try next year. The audit should cover six key areas: objectives, channels, campaigns, workflow, resources, and outlook. By analyzing these areas with thought-provoking questions, marketers can gain insights into their past year's work and make informed decisions for the upcoming year. The process is designed to be simple and accessible, even without fancy tools or a lot of time.
