A Theory of Control
My idea of happiness is directly related to the concept of control. First and foremost there is the idea of self-control. The only real power that matters in the end is power over yourself and the ability to master your emotions. Top on the list is impatience, your need for immediate gratification. Other emotions would be fear, which must be confronted and faced down. The desire to be liked and admired is an equal impediment, as is uncontrollable anger. You can never gain complete control over these emotions, nor would you want to. All that is asked is more control than you had in the past, more control than your rivals. The clearer your head is of such emotions, the better strategies and decisions you will hit upon.
Directed outward, this means controlling to some extent the actions of your rivals. Observing various war I came to the conclusion that the winning side had inevitably gained control over the dynamic. This idea started to obsess me. I realized that this was a key to not only warfare and strategy, but to almost all aspects of life in which there is competition.
