Challenges of life remind me of my days in senior high school which I joined in the military training. It was the first time I have lived far away from my home, so I found difficult to fit in. And the trained officer was strict with me. I once think I could not stick to the end. And anyway, I succeeded. The trials made it much easy for me to adapt to life, and the difficulty I came across have now all become a precious memory in my life. In a short, I have learned to regard the challenges of life like a stepping stone to future success.
