The modern fantasy about wow, business is changing so quickly, you've got to keep morphing and changing, updating your brand, getting a new visual identity. All of those things, they're just bad, bad, bad, bad, bad. Don't do them. Why? It's because you interrupt habit. So rather than a consumer thinking about, oh, wow, I am loyal to, let's say, Tide. I'm loyal to Tide detergent. I really should buy it. It's actually that person's subconscious saying, you know, the most comfortable thing to do, the thing we... in your subconscious are most confident of is that thing that worked for us before. So please, please, please don't think about buying something else. Tide's been around for 76 years, and it has what we call cumulative advantage. Cumulative advantage is what you increasingly build as the customer becomes more and more comfortable with using your product or service. Each time they use it and get the benefits they wish, you get more cumulative advantage that causes the subconscious to say I'm totally comfortable with this and I would be uncomfortable if we did something else. That's the win of cumulative advantage.
