The 48 Laws of Power - Robert, G. (2000).

If you are unsure of a course of action, do not attempt it. Your doubts and hesitations will infect your execution; Timidity is dangerous: Better to enter with boldness. Any mistakes you commit through audacity are easily corrected with more audacity. Everyone admires the bold; no one honors the timid. 227 Law 28

It is tempting to want to fix our mistakes, but the harder we try, the worse we often make them. It is sometimes more politic to leave them alone. 306 Law 36

Using words to plead your case is risky business: Words are dangerous instruments, and often go astray. The words people use to persuade us virtually invite us to reflect on them with words of our own; we mull them over, and often end up believing the opposite of what they say. (That is part of our perverse nature.) It also happens that words offend us, stirring up associations unintended by the speaker. 313 Law 37

The reason arguments do not work is that most people hold their ideas and values without thinking about them. There is a strong emotional content in their beliefs: They really do not want to have to rework their habits of thinking, and when you challenge them, whether directly through your arguments or indirectly through your behavior, they are hostile. 322 Law 38

Anger only cuts off our options, and the powerful cannot thrive with out options. Once you train yourself not to take matters personally, and to control your emotional responses, you will have placed yourself in a position of tremendous power: Now you can play with the emotional responses of other people. Stir the insecure into action by impugning their manhood, and by dangling the prospect of an easy victory before their faces. 330 Law 39

Understand: With one exception -- death -- no lasting change in fortune comes quickly. Sudden wealth rarely lasts, for it is built on nothing solid. Never let lust for money lure you out of the protective and enduring fortress of real power. Make power your goal and money will find its way to you. 337 Law 40

Powerful people never waste time. Outwardly they may play along with the game-—pretending that power is shared among many but inwardly they keep their eyes on the inevitable few in the group who hold the cards. These are the ones they work on, When troubles arise, they look for the underlying cause, the single strong character who started the stirring and whose isolation or banishment will settle the waters again. 363 Law 42
