The Chofetz Chaim writes (Sefer Toras Habayis 2:3) that in one minute, a person can say 200 words. This means that one can say several thousand words of Torah every day, and each word is a mitzvah in and of itself. Through these words of Torah, one can create thousands of angels every day, which speak in his defense.
Therefore, he writes, how could anyone not learn with enthusiasm? Knowing how much one loses when he wastes time, how could one not properly use each day?
