Lack of confidence can be "smelled" a mile away. Negativity, cynicism, and a "poor-me" attitude is not attractive at all—no matter how you try to mask it.
While it may seem too simple and bordering on just "self-help" talk, the beliefs we hold about ourselves are fundamental in our success. The concept of reversing negative internal narrative seems simple; however, actually changing what you are thinking, feeling, and exuding is not—but it can absolutely be accomplished!
We guarantee that if you have lost the job offer, perhaps even during a second interview, the person who got hired sold their qualifications with more confidence, was more persuasiveness in promoting their value, and closed the deal (job) by assertively reassuring the employer that they were the best choice!
