Challenges of life are of great importance in our grow. They remind me of my days in senior high school which I joined in the military training after I entered senior high school. It was the first time that I have lived away from my home, so I found it difficult to fit. And the training officer was strict with me. I once thought I couldn't stick to the end. But anyway, I was succeeded. The trials made it much easy for me to adapt to life, but I think the difficulty I came across have now become a precious memory in my life.

In short, learning to regard the challenges of life as the stepping stone to future success and make the best of them.
