"If you praise people and treat them as if they’re being their best selves, and point out all the positive things they do and what you like about their behaviour, they’ll do more of it, and they’ll do their best to live up to that expectation.
Same goes for if you treat them as a loser and only point out what they’re doing wrong, they’ll live up to that as well."
