I smile because I have survived everything the world has thrown at me. I smile because when I was knocked down, I got back up.
Having gone through so many difficulties, so many incidents, it seemed that those hardships had defeated me. But no, I got over everything.
Now I can smile because I have faced and was strong to overcome those obstacles in my life which was about to drown me. Because I did face with unhappiness, I can overcome it.
The whole world was against me, I was persistent and determined to win it, and I did it. Even when I had collapsed, my mind still reminded me that I must not give up, must not fail.
I stood up again, steadily, and more resiliently than before. I smiled because I won against the fate, again myself.
