The act of going about to solicit or obtain an office, or any other object of desire; canvassing.

An eager, and sometimes an inordinate, desire for preferment, honor, superiority, power, or the attainment of something.

a cherished desire; "his ambition is to own his own business"

a dream that a person desires to achieve at all costs and therefore if you do not attain that challenge it keeps on haunting you because you have spent a lot in terms of time and money and you do not believe you are nowhere

To certain people, ambition may be deemed pointless, vicious, "perverse" in an unjust society "arising from a lack of ability", a "dirty little secret", the dark side of self promotion, careerism, opportunism, or best kept hidden (as in Jay Gatsby, Sammy Glick, Uriah Heep). However, to career management professionals, ambition is an "ardent desire for rank, fame, or power", the "fuel and oxygen of achievement", intrinsically healthy, innate, a foundation for developing the complete person, a way of forming our own destiny.

One's goal and desires in life (i.e. career goals).

the systematic pursuit of achievement and of constant improvement in respect to one's goals

If you gained it in your dream, be prepared for a setback; but if you were frustrated in your dream you will attain your objective in time.
