Bravest moment of my life.
I am not sure whether i can think bravest moment as the coolest moment of my life, but if can, that = the bravest moment of my life is same as the coolest moment of my life but if it is, it was the time i passed the exam to enter university. I was kind of late bloomer because I started to study late than the others. I made up my mind to enter university when I was in the army. So during my military duty, I tried to spare some time to study. It wasn't easy for me to do both my duty and the study, but I made zealous effort and nailed it.

Is my HW short or long? I'm not sure about the length.. Thank you.
