People who are successful in business or in public life must take danger into consideration.
History teaches us that there is always someone who has sufficient reasons to be your enemy. Therefore, you should not underestimate the role of personal safety.
All actions aimed against your family, professional and personal life violate your safety. This may take the shape of punishable threat, blackmail, fraud, kidnapping, assault, extortion, slander, spoiling a brand name or sabotage. If you lack proper knowledge, it costs you loss of time, money, health, or life.
Perhaps you had no time to think about these matters when you were developing your business or holding a position.
But from a certain level on it is a must. Protect your hardly earned property and social position.
