How to Win Friends and Influence People

Carnegie teaches that leadership hinges on the ability to guide others without inciting resentment, and to this end, he advocates for avoiding outright commands and leavening criticism with sincere praise. He cites the example of successful steel magnate Charles Schwab, who always made it a point to “praise” his employees and actively avoided delivering criticism. This approach translates well to any professional sphere. If a manager needs to address an employee’s mistake, the conversation should begin with an acknowledgment of the employee’s past contributions, as this gentler lead-in will preserve morale and forestall a defensive reaction. Modern leadership theorists often refer to this technique as “the feedback sandwich” and suggest enclosing criticism between two layers of encouragement to lessen the sting of the constructive feedback. A practical example can be seen in effective teacher-student dynamics. In this scenario, a teacher who praises a student’s improvement before gently correcting a mistake can more effectively build rapport and inspire continued effort. Carnegie’s advice is designed to make others feel appreciated and inspire trust and receptivity in the midst of difficult conversations.
