A 99 once made me feel invincible, but when the next paper came back 96, fear pounced like a shadow. So I built a notebook of every stumble, turning red ink into rocket fuel. Edison taught me that each “wrong” answer is just one filament closer to light. Today I roar: failure isn’t a verdict; it’s a map. Open your mistake notebook, keep moving, and watch fear become the loudest cheerleader you’ve ever had. My name is Leo, I am7 years old.I like reading English picture books, and I am fond of Go and martial arts. I want to be a scientist, and my favorite is the great inventor Edison.
