When we say “Modeh Ani,” we often focus on the word “Modeh," thanking Hashem for returning our neshamah to us each morning.
However, we should also focus on the word "Ani," I. We are not merely thanking Hashem for giving us another day of life; we are thanking Him for making us the way He did. He gave each of us our unique personality, our individual character traits, our talents and abilities, and our particular strengths. He gave us our parents, our upbringing, our experiences and all the circumstances that shaped us into the people we have become.
"Modeh Ani" is therefore an expression of gratitude not only for what we have, but for who we are. Before we even begin the day, we recognize that the “Ani," the person standing here this morning, is itself a gift from Hashem.
