Omar Khayyam. (№ 6587)

That wisely a life to live, ought to know a lot.
Two important rules to remember the beginning:
It is better to starve than horrible there,
And better alone than with just anyone.
(Above all the teachings and rules of how to live,
Two principles of dignity I chose to adopt:
Better not eat anything than eat that horrible;
It is better to be alone than with just anyone to be friends.)
