Undergraduate / "scrupulous in everything" - Ohio State: What is one thing you do really well? [6]

Consider your talents and strengths, academic and otherwise. What is one thing you do really well?

Hello,everyone. I am applying for the Ohio State University, and this is my draft to this question. English is my second language and I am not very good at it, so there may be a lot of grammatical mistakes in this essay. Any suggestion will be appreciated, and I want to say thanks in advance.

If I can only say one thing I do really well, I believe it is that I can be scrupulous in everything. I didn't realize why a man should be patient with his work until I was in high school.

I was the Minister of Health in the student government in high school, and one of my important jobs was to supervise the students to clean the school compound. I was not so careful about this task at first. I just wandered around the main roads to see if there if the students had cleaned them, and I seemed to be very good. However, after a few weeks, when I adventitiously passed by a corner of the school, I found a large pile of trash, smelly, with a large quantity of flies around it. It is shameful that I didn't even know this situation before just because of my carelessness.

I dealt with the problem immediately. What's more, I have learnt to be always scrupulous in my work. With patience, I found myself able to study more efficiently, and work better.
