Erich Fromm said this quote
“ When a person feels that he has not been able to make sense of his own life, he tries to make sense of it in terms of the life of his children. But one is bound to fail within oneself and for the children. The former because the problem of existence can be solved by each one only for himself, and not by proxy; the latter because one lacks in the very qualities which one needs to guide the children in their own search for an answer. ”
