I realize that whether it's from 0 to 1 startups or from 1 to 10 startups, everyone is spending a lot of time satisfying their own demands rather than the customers' demands. For example, my short videos must go viral for me to keep posting, otherwise my confidence will be hurt. This has nothing to do with the business; it's purely a personal demand. Jia Guolong insists on "making a statement," which is similar. This is disguising self-emotional demands as business goals. According to subjective value theory, the premise of exchange is: the customer believes that "the value of the product" > "the value of money." Always treating oneself as a consumer in a production environment... As a human-machine, I cannot empathize with this.
