What is ambition?

To me, ambition is a strong desire to do or to achieve something which can require determination. At times, when someone has an ambition it can either be positive or negative because that someone can have the ambition to do something either really good or really bad. When I think about ambition, I think of it as something that really drives someone to accomplish a goal, making it so that they are really determined and focused to achieve that goal. An example of a positive ambition will be somebody who wants to become a doctor and possible find a cure for a certain disease. The reason for this being positive is because finding a cure for a disease will have a positive effect on the world by reducing the number of people with the disease which a cure was found for. An example of a negative ambition is someone who is driven to get revenge on somebody by either killing them or doing what ever. This is a negative ambition because most of the time violence is not the solution because morally it is not right and it can usually get you into trouble.
