Challenges of life are of great importance in our grow. It reminds me my days which I joined in the military training after I entered senior high school. It was the first time I have lived away from my home, so I found it difficult to fit in. And the training officer was strict in me. I once thought I couldn’t stick to the end. But in anyway, I made it. The trials made it easy for me to adapt to life, but the difficulties 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.
