Life, how much pain, there will be how much growth. The beautiful butterfly moults into an adult insect many times in its life, and experiences a long loneliness in the chrysalis before it emerges as a butterfly. A fall into the pit a gain in wisdom, the growth of life is also accompanied by deep or shallow wounds. Pain, not terrible, you dare to face, it is a kind of medicine. The worst fear is that you will finally get through the pain and collapse on the brink of victory. The most beautiful smile never blooms at the end of the pain.
