It is very sobering to realize just what the future holds for a boy of my age. On the other hand it is a practical challenge to a man's courage and personal integrity. A man who talks but is afraid to act, who sacrifices principle to expediency whenever real danger threatens is not worthy to keep and enjoy what he has. He is not worthy of his background and heritage who kowtows to tyranny in order to cling to his temporary safety and comfort... I trust I will have the courage to act as I speak come what may. I will not be easy – but should, therefore, can be done.
