You cannot hope to build a better world without improving the individuals. To that end each of us must work for his own improvement and, at the same time share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful.
What we call our destiny is truly our character, and that character can be altered. The knowledge that we are responsible for our actions and attitudes does not need to be discouraging, because it also means that we are free to change this destiny. One is not in bondage to the past which has shaped our feelings, to race, inheritance, background. All this can be altered if we have the courage to examine how it formed us. We can alter the chemistry provided we have the courage to dissect the elements.
