This is a great prompt which I wrote about previously. It is a topic close to my heart. The day after completing my doctoral degree I realized that I knew nothing and possibly what I will learn in this lifespan would not be a drop in the ocean. Your conclusion articulated it beautifully. You inspired me to write about it from a different angle. Your polymath abilities are noticeable in your prolific writing. Thank you for sharing your reflections beautifully.
