Heredity is what sets the parents of a teenager wondering about each other.

Our character is not so much the product of race and heredity as of those circumstances by which nature forms our habits by which we are nurtured and live.

Acceptance of one's life has nothing to do with resignation it does not mean running away from the struggle. On the contrary it means accepting it as it comes with all the handicaps of heredity of suffering of psychological complexes and injustices.

We do not know in most cases how far social failure and success are due to heredity and how far to environment. But environment is the easier of the two to improve.
