Burning Popcorn at the Movies - Stanford Activities Essay

Any thoughts on my activities essay for Stanford? It was the only thing I could really think to write about.

Briefly elaborate on one of your extracurricular activities or work experiences. (150 word limit)
I burnt the popcorn on my first day at work. The kettle is supposed to be turned over once the popping slows down, but I misjudged what "slows down" actually meant and let it burn. The smell pervaded the room and probably scared off some customers. That same day, I burned myself trying to clean the kettle, and it took me an extra hour to close down. Although at the time this experience made me question how I had gotten hired in the first place, I now see that setting me loose so soon was meant to be a teaching experience; I learned from my mistakes and improved exponentially.

So far, working at a movie theater has taught me about time management, responsibility, and commitment. More importantly, it has taught me to appreciate the hard work my parents put into supporting our family. Plus, I make a mean pretzel now.

Your statement is clear and prompted, however I think you should put more meaning into the last sentences about what it has taught you for the future. Other than that, extracurricular activities is straight forward.
