To truly change a brand's narrative, marketing's 'talking the talk' is insufficient. The product experience itself must embody the desired story. This 'walking the walk' through the product is the most powerful way to shape core brand perception and make the narrative shareable.

When building a brand, differentiate between long-term and short-term elements. The core purpose and emotional connection should be enduring. In contrast, functional and experiential benefits must be constantly refreshed to remain relevant as markets and consumer tastes evolve.

Unilever uses its SASSY framework (Science, Aesthetics, Sensorials, Said-by-others, Young-spirited) to create desirability. This model systematically elevates brands from functional "needs" to emotional "I have to have that" wants, applicable even to everyday products.

Enduring 'stay-up' brands don't need to fundamentally reinvent their core product. Instead, they should focus on creating opportunities for consumers to 'reappraise' the brand in a current context. The goal is to make the familiar feel fresh and relevant again, connecting it to modern culture.

Most product categories are commodities with minimal functional differences. Success, as shown by Liquid Death in the water category, hinges on building an emotional connection through branding and packaging, which are the primary drivers of consumer choice over minor product benefits.

Coca-Cola markets a sugary beverage with no nutritional value by completely ignoring product attributes. Instead, its brand is built on emotionally resonant stories of happiness and togetherness, proving that a powerful intangible idea can be more persuasive than the tangible product itself.

In a crowded market, brand is defined by the product experience, not marketing campaigns. Every interaction must evoke the intended brand feeling (e.g., "lovable"). This transforms brand into a core product responsibility and creates a powerful, defensible moat that activates word-of-mouth and differentiates you from competitors.

The "Got Milk?" campaign illustrates how to build a powerful brand for an undifferentiated commodity. By focusing on the emotional, everyday experiences associated with the product, it created cultural relevance and affective importance, effectively raising the profile of the entire milk category rather than a single company.

Coca-Cola pioneered lifestyle advertising by shifting from promoting intrinsic product qualities (a "brain tonic") to extrinsic associations. They linked the brand to universal positive emotions like happiness, friendship, and Christmas, making the product a symbol rather than just a beverage.
