When opponents are unwilling to fight with you, it is because they think it is contrary to their interests, or because you have misled them into thinking so.
—Sun Tzu
We all have to fit in, play politics, seem nice and accommodating. Most often this works fine, but in moments of danger and difficulty being seen as so nice will work against you: it says that you can be pushed around, discouraged, and obstructed. If you have never been willing to fight back before, no threatening gesture you make will be credible. Understand: there is great value in letting people know that when necessary you can let go of your niceness and be downright difficult and nasty. A few clear, violent demonstrations will suffice. Once people see you as a fighter, they will approach you with a little fear in their hearts. And as Machiavelli said, it is more useful to be feared than to be loved. Uncertainty is sometimes better than overt threat: if your opponents are never sure what messing with you will cost, they will not want to find out.
Daily Law: Build up a reputation: You’re a little crazy. Fighting you is not worth it. Create this reputation and make it credible with a few impressive—impressively violent—acts.
