The more obsessed you are to a cause or vision or goal, the more dedicated, absorbed, and focused, the more dominated and possessed by the compulsion to analyze and act and repeat with persistence, like an addiction, like a hunger, like your life depends on it, no matter the struggle or set back or stagnation… the more successful you’ll be.
Some people balance this better than others.
Some are more neurotic. Some are more composed.
But in the end, your level of consuming obsession dictates your ability and speed of accomplishment.
