People buy the why.
A lot of marketing goes wrong when they start selling the "what" of their product instead of the "why".
People don't care what you've made and are now selling. They only care about their problems. They only care about how your product can help them solve their problems. This is the "why".
The best brands in the world are built around "why". Let's take Coca cola, in all its advertisements the focus is on selling happiness. If you buy coke, you buy happiness. That's the narrative they're trying to sell.
And it works. Coca cola is one of the most solid brands built till date. The company has been doing well for 100+ years and the product hasn't changed much with time.
If you're into marketing. Sell something that people want, like happiness. This is how the best brands are built.
