I think you’re right that I’m a negatively biased person, so the praise may have been received differently if I was a more positive person. However, the outcome of the praise was that I was never self-confident and had/have low self-esteem. I think what I received was closer to “you’re the smartest kid” and that set me up believing I was destined to be the _most_ successful adult even if I never felt capable of achieving that.
It depends how it was told. Being told "you are smart" vs. "you are the smartest kid" makes a big difference.
