some nordic/germanic cultures have a funny social custom. if you become too important, famous or successful, it is the job of your family and friends to tease you and pull you down so you dont get a big head. it seems counter intuitive, but its important, imho, to stay humble and grateful for the people who made you who you are.
this is tricky because we tend to do looking for encouragement from strangers, who arent socially invested in our success.
healthy self esteem and parenting is a challenge to create. it constantly surprises me that we dont think more about psychological needs when raising and educating children.
