Ambition vs Aspiration

“According to the Merriam-Webster dictionary, ambition is defined as an ardent desire for rank, fame or power, while aspiration is defined as a strong desire to achieve something high or great.”

I have forever used these words interchangeably. Wanting to achieve something great does not always have to do with rising in rank, fame or power. It is perhaps when we confuse the two goals that we miss the plot for why we do what we do.
