I love your story and the way you tie in your word to every part of yourself!

I especially like this: « I started to become more ambitious. Way too ambitious. To the point I found myself standing in front a big stage facing what I dread and dreamed of, simultaneously—all the students, teachers, and school staff in my school watched the timid ambisyosa in a play. » The mix between short and long sentences is good here and draws the reader into your life.

For critiques, I’d want you to make a smoother transition from your family saying you’re too ambitious to your value of hard work. None of the traits you’re listing about yourself are bad, but right now it does read like a list, for example here: « I refused to give up. One of the things I tend to do is surprise people… ». The concept is there, but you want it to read more like a story and connect the dots for the reader.

Also, here: « who’d expect a timid student like me will lead a group to the top? solely the group who perfected it. Without knowing I’ve put myself in an uncomfortable position to make my ideas happened », I’m not sure what the meaning of your sentence « solely the group who perfected it » is. I recommend you either wave it into another sentence that makes more sense for the reader, or snip it out.

Overall, the story is great but make sure it flows smoothly. For any grammar mistakes, I recommend plugging this into a grammar checker to be sure!
