Ambition is defined as a strong desire to do or to achieve something, typically requiring determination and hard work.
However when I read that definition the second half of the sentence really stuck out to me. Determination and hard work are typically required. So when you are analyzing your ambitions in life, does it contain hard work? Does your work ethic towards your life goals reflect hard work? Ask yourself is this truly a desire of my heart or something I periodically enjoy doing.
