I said there was but one solitary thing about the past worth remembering, and that was the fact that it is past-can't be restored.
Mark TwainWhen I was fourteen, my father was so ignorant I could hardly stand to have him around. When I got to be twenty-one, I was astonished at how much he had learned in seven years.

Prosperity is the best protector of principle.
Mark TwainWell, my book is written-let it go. But if it were only to write over again there wouldn't be so many things left out. They burn in me; and they keep multiplying; but now they can't ever be said. And besides, they would require a library-and a pen warmed up in hell.
