"Know your Ruling Star. One man is better received by one nation than another, or is one welcome by one city than another. He finds more luck in one office or position than in another, and all though his qualifications are equal or even identical. Let each man know his luck as well as his talents. Follow your guiding star and help it without mistaking any other for it. Know how to transplant yourself. There are nations with whom one must cross their borders to make one's value felt.
