Writing Feedback / Writing an Essay on Personal Growth based on an activity [2]

I am writing my first essay for a college program at Yale. I am a native German speaker, but I do go to an American high school. I'm in desperate need of some feedback on my essay. The prompt is:

Please describe the activity on your resume or activities list that you think has elicited the most personal growth and why? (200-word limit)

"drawing with lights"

Photography is a method of recording an image on light sensitive objects or paper. The process corresponds to the Greek translation "drawing with lights." Most people will say that taking pictures, looking through a camera is the best part of photography, but I believe the best part is working in the dark room. Enlarging an image, manipulating them and watching it appear is amazing. The process of developing the film to enlarging it has taught me patience in all aspect of my life. In photography, I never truly know if the film was exposed correctly or if the enlarged image will look right, so I need to be patience until the very end. I also learned time management because the deadlines in my photography class are very strict and the process takes a few day. Therefore, I always need to plan out my week depending on what is due when, so nothing is late.
