Build products on simple, foundational concepts rather than complex, rigid features. These core building blocks can then be combined and layered, leading to emergent complexity that allows the product to scale and serve diverse needs without being overwhelming by default.

Audiences forget 90% of what they hear within 48 hours. To ensure your key point is remembered, you must proactively define your single "10% message" and repeat it frequently. Otherwise, the audience's takeaway will be random, preventing unified understanding and action.

Trying to be overly clever with metaphors or complex language can distract and confuse an audience. Simple, direct narratives—like a "Dick and Jane" book—are more effective because they ensure the core message is easily understood and retained.

Limit your key points, pain points, or takeaways to three. This cognitive principle makes information easier for prospects to receive, understand, and retain, preventing them from being overwhelmed by too much information.

The human mind rejects ideas that are too novel. Effective communication and innovation should be grounded in the familiar, introducing only about 20% new information. This principle, from designer Raymond Loewy, helps make new concepts intelligible and acceptable.

Effective communication requires a careful balance. A clear structure makes your message easy to process and prevents cognitive overload, which listeners find aversive. At the same time, novelty and surprise are necessary to maintain interest and prevent boredom. One without the other fails.

Leaders often feel the need to create new metaphors for every presentation. However, audiences require hearing the same core message multiple times to absorb it. The key is to embrace the mantra "repetition never spoils the prayer" and focus on consistently delivering a few key themes.

Extensive behavioral research on ad performance reveals a clear pattern: simplicity is superior. Creatives with multiple storylines, clutter, and excessive detail create cognitive load and reduce effectiveness. The best-performing ads feature a single, clear message that is easy for the human brain to process quickly.

When presenting a long list of actions, such as ten ways to improve a team, group them into three distinct, memorable categories. A coach successfully reframed ten tips into a three-step framework of 'alignment, process, and resilience,' making his advice more digestible and actionable for the audience.
