Answer:
A fiery ambition would be an act of desiring with aggressiveness or explosiveness.
Explanation:
All right this is a very brilliant arrangement of literary resources. But we need to understand it.
Fiery is a word that comes from fire, then it provides the heat, the damaging and harmful elements of fire.
Ambition is the act of desiring something with big emphasis. It also implies a very big effort to achieve that desire.
Thus fiery ambition can be pictured as desiring something with aggressiveness, with passion, with explosiveness. So it is a very brilliant combination of words because ambition by itself is already an exponential word. But adding the fiery adjective provides it with a stronger force.
