24x7 novelty
I don't think there are many bands who play a different setlist every time they perform. They might change a few songs and create some surprises along the way, but nothing more.
It's impossible for the local ice cream parlor to dish out a new flavor of ice-cream, every day.
The same goes for the teacher who teaches the same subject year after year. The syllabus and students change but the subject matter largely remains the same.
The same applies to your marketing. You are saying the same thing to your customer over and over. You can change how you say the message, but for the most part, you're saying the same thing. And that's fine. Novelty and change are good once in a while. Yet, a lot of emphasis is given to novelty. That's why we constantly check our social media feeds.
What's new? What's different? What did I miss? Sure enough, the returns on this are negligible.
I'm not sure everyone is always looking for novelty. They're looking for dependability and comfort. They want to feel like they matter and they want to feel engaged. After a class or an interaction with a product, they don't want to feel like they wasted their time.
In reality, it's the consistency that saves the day. If the teacher, marketer, or chef doesn't enjoy the grind, novelty isn't the answer.
