Your attitude directly impacts how you communicate and collaborate with others, contribute to the culture of your work environment, and perform your daily tasks and responsibilities.
My book, "Finding the Best Version of Ourselves: The Interview of Self," essentially argues that when you are indeed "authentic"—meaning you are acting in line with your core values and beliefs—you will naturally gravitate towards goals and opportunities that align with your true self. A negative attitude would contradict this authenticity by pulling you away from what genuinely resonates with you.
