Never marry a woman you wouldn’t wish to divorce, i.e. never get into a position you couldn’t get out of with ease, and think of this before you make the commitment. I would add that the selfish wife or selfish price or selfish dog should never marry a man that will leave her in oblivion if things don’t work out. Imagine the great harm that the selfish dog did itself by killing a human. Now they’re all likely to be rounded up.
Never admit to having made a profit, but always emphasize your losses.
Surround yourself with big and powerful players so that your positions will be with the forces when you disseminate or implement them.
