As by the fires of experience, so by commission of crime you learn real morals. Commit all crimes, familiarize yourself with all sins, take them in rotation (there are only two or three thousand of them), stick to it, commit two or three every day, and by and by you will be proof against them. When you are through you will be proof against all sins and morally perfect. You will be vaccinated against every possible commission of them. This is the only way.
Mark TwainAll my life I have been honest-comparatively honest. I could never use money I had not made honestly-I could only lend it.
Mark TwainThere's plenty of boys that will come hankering and gruvvelling around when you've got an apple, and beg the core off you; but when they're got one, and you beg for the core, and remind them how you give them a core one time, they take a mouth at you, and say thank you 'most to death, but there ain't a-going to be no core.
