I believe that we were not taught as children how to love ourselves so this perpetuates throughout the entire generations.
Self doubt is instilled early in our society. Advertisements show us what we need to buy in order to become more lovable or accepted. This is why many of us grew up as adults thinking self doubt is normal.
I do hope that inner healing towards self love will produce changes in the upcoming generations, too many teens and even children are depressed today because they lack self love, the kind of self love the did not see in their parents... Children mirror a bigger picture of the society's malaise
