I've always asked myself this question. I recently finished watching Narcos and as we know, Pablo Escobar was the boss. Now, in a "legal" business like Microsoft, Bill Gates was the boss because well, he invented it. But when it comes to the drug business, Pablo had rivals and killers working for him. How did he manage to keep them under control without someone in his crew saying "fuck it I'm gonna kill him so I become the boss" ? In a legal business you can't just kill people until you reach the top, you have managers who can fire you and all that, but if someone's your right hand and he wants to be the billionaire boss, what stops him from doing that ? Is there like a book to learn how to be a leader or is it possible that some people are just natural born leaders ?
