There are many people in the world who lack ambition. They have no dreams that they live for. They have no aspirations. They just live; depend on others; and wait for the wind of life to toss them to any direction.
If too much ambition is bad,not to have ambition at all may be worse. Ambition is what drives people to bring out the potential that is buried in them; to do things and to take the world to higher levels of progress.
If you are among the billions of people who lack ambition, do well to change. Right away, decide what to become; and it should be better than what you are at the moment. Bear in mind that God made you for great things; and you can be one of the shining and sparkling persons of the world.
