Is anyone capable of becoming a captain of a ship?

 I do not believe it is possible for anyone to become the captain of a ship. There are certain strengths that a captain must possess in order to be successful. If they do not possess these strengths to a great degree, then they will never even come close to reaching the position of captain. One key strength a captain must possess is the ability to put mistakes and misfortunes behind them quickly. For example, if a captain's crew is in a battle with pirates and his closest shipmate gets shot and killed, the captain must be able to remain focused and not waste a split second in distraction. They must remain focused and give out commands to his shipmates quickly and precisely in order to avoid more casualties. Some people are just not capable of doing this. Certain people are simply too sensitive to tragedies and get too emotionally shaken, preventing them from being fully dedicated to the mission. Another key attribute that a captain must possess is the ability to remain slightly separated from the rest of the crew. The captain has to be very authoritative at times and may have to suffer the resentment of their crew. If a captain allows himself to become too close to the people under him, he may be hesitant and unwilling to exert his authority because he begins to care too much about his image and friendships. If this happens, the crew will lose order at times and will be unprepared to face certain challenges at sea. Certain people are just not capable of maintaining this distance between the people under them. They may simply be too friendly or gentle to shift into the stern and cold mood that is sometimes necessary to command a ship.
