Ambitions are the desire, to achieve something, or to succeed, accompanied by motivation, determination, and internal desire.
Ambition describes those that achieve success based on their inner desire to do so and their belief in themselves. Ambition in itself may not be a key to success. Successful, ambitious people need both energy and goals to succeed. Someone with plenty of energy but no goals may find themselves pursuing one opportunity after another without success, wondering what it is that they are wanting out of life.
Someone with goals but no energy may find themselves wanting to achieve success, but too complacent to do the work to go about pursuing their goals.
