one day, i saw people making beautiful things from sand, and they called it glassblowing. it was like they were magicians turning something from the ground into shiny, clear treasures. i learned that a long time earlier, someone came up with this concept, but they had to practice a lot and couldn't neglect learning every day. and if they made a mistake, it was okay because they could just begin afresh, like being undercover detectives finding out the secrets of glass by trying again and again until they made something beautiful.
