I've made a couple of edits to some of it, which improve the overall grammatical structure as there were some mistakes made in the same. Written a few suggestions/comments in red.
A good leader possesses many different qualities but, in my opinion, every good leader has three defining qualities : good logical reasoning, quick decision making, and patience. Although there are other characteristic qualities such as having good etiquette and good people skills, but the three that I mentioned are the most important.
First of all, a good leader should think logically. In soccer, captains lead other players on the pitch. A good captain chooses the most ideal location from which he can survey his team and the pitch. He also organizes defenders and strikers. These types of leading roles require good logical reasoning. For example John terry is captain of England's football team as well as the captain of Chelsea. As I am a fan of this soccer player, I have always carefully observed him. I see how he organizes defenders and leads the rest of the team and, in my opinion, he is a born leader.
Second of all, a good leader is a quick decision maker. A quick decision has many positive consequences such as saving money, time, and energy which are important to big companies. Heads of companies are good examples as most of them are bold, who take calculated risks. In today's competitive world, there are many companies who are in a constant competition for the top spot and for them timing is a crucial parameter. A good leader makes the right calls at the right times, leading his company to success. I don't know, something about the example you've used here doesn't feel right. Maybe you could think of a different, perhaps more personalized, kind of example for this characteristic quality.
Finally a good leader is patient. Sometimes companies face many problems such as financial problems. At this time the head of the company patiently takes the company through the thick, just like the captain of a ship navigates it through storm. Financial problems, workers strike and fires in the factory, are like storms that a good leader would face and would find solutions for patiently, save the company from potential bankruptcy. Example isn't well-applied. Similar company example already used in the previous characteristic. To give your essay more variety, you should use a different kind of example here. Otherwise, using 2 of the same examples and 1 radically different (Football) doesn't really leave a nice effect on the reader, in my opinion. Also, you should connect your characteristic much more deeper with the example you have used.
In summary being good at logical reasoning helps a leader to lead others, making quick decisions is sometimes important, and being patient helps a leader to solve problems. These are the true qualities of any good leader.
