I know in my heart that man is good. That what is right will always eventually triumph. And there?s purpose and worth to each and every life.

The ultimate determinant in the struggle now going on for the world will not be bombs and rockets but a test of wills and ideas-a trial of spiritual resolve: the values we hold, the beliefs we cherish and the ideals to which we are dedicated.

To sit back hoping that someday, someway, someone will make things right is to go on feeding the crocodile, hoping he will eat you last–but eat you he will.

There are no great limits to growth because there are no limits of human intelligence, imagination, and wonder.
