My friends, when you are most pessimistic and disappointed, that's when you have to build up strong confidence. You have to believe that there is no wasted effort in the world. I don't have to succeed, but I don't have to donate my skills. If pain is a bitter wine, drink it quietly; if pain is a scar, make it a smile on your face. Some words, suitable for rotten in the heart, some pain, suitable for silent forgetting. When experienced, the pain in the heart eliminated in the invisible, you grow up, you know well. A lot of changes, you don't need to say it yourself, others will see it. Learn to understand to share, in fact, each of us is happy. Just, your happiness, often in the eyes of others. The mountain of happiness has no top and head. You should learn to walk and stop, look at the mountain haze, admire the rainbow, blow the breeze, and get the satisfaction of life in relaxation.
