He is full of ambition and energy.A person shrinks or expands into the degree and nature of his ambitions.

For instance, in a family of several children, the youngest child compares himself to his older siblings, and, falling short, might become highly competitive and ambitious, or, conversely, withdraw in the belief that he is fundamentally inadequate.For a man whose ambition had always been to farm, he has no regrets about his change of career.

The opposite of hope is, hopelessness, or despair; the opposite of ambition is simply lack of ambition, which is not in itself a negative state.The first instance (kicking the dog) is an example of displacement, the redirection of uncomfortable feelings towards someone or something less important, which is an immature ego defence.The present trustees could never be accused of lacking ambition.
