Boss: "You need to be confident and successful."
Employee: "I understand that. But how?"
Boss: "You need to be confident and successful."
Employee: "Can I have a raise?"
Boss: "You need to be confident and successful."
Constructive Pain
Boss: "You need to be confident and successful."
Employee: "I agree. How?"
Boss: "Be passionate and curious."
Employee: "I understand that. But how?"
Boss: "If you don't know, maybe you should search for the answer."
Employee: "Can I have a raise?"
Boss: "You need to be confident and successful."
