The Merriam-Webster Dictionary’s definition is

b : desire to achieve a particular end
2: the object of ambition <her ambition is to start her own business>
3: a desire for activity or exertion <felt sick and had no ambition>
My definition is: ambition keeps me awake at night as much as it makes me get up in the morning with the sense of accomplishment. It proves I am a good mother and makes me work hard. Ambition can be seen in people’s eyes, it shines and looks higher. Ambition is something I cannot imagine living without.
