There are some companies that have learned their marketing lesson. There are companies that have found and can utilize their unique selling proposition (USP). And there are no other companies. Going to the market without something unique leads to devastating results. Have you ever seen or heard a commercial that says: “We have the same product like XXX, but worse, more expensive AND with less features.”
This assumption is true both for your business and for your personal self. Don’t start your business, unless you know you can do something in a unique way. And don’t go to an interview to one of the top companies in the world, if you don’t know that you going to offer them something unique.
