Put aside your need for a step-by-step manual and instead realize that analogies are your best friend.
When the room brightens when you walk in, you matter.
Great marketers don't make stuff. They make meaning.
If you're remarkable it's likely that some people won't like you.
You don't have enough time to be both unhappy & mediocre. It's not just pointless; it's painful.
Stop trying to find the formula that will instantly make your idea into a winner. Instead of being scientists, the best marketers are artists. They realize that whatever is being sold is being purchased, because it creates an emotional want, not because it fills a simple need.
