Someone asked me if I envied my friend's marriage. I said, I was envious, not that she was married, but that I envied her heart that dared to be happy and was willing to be happy. Many times, it's not happiness that forgets to knock on your door, but you yourself that forgets to open the dusty lock on the door. We work hard, we are proactive, we work hard, and keep running forward, but we always forget to take a look at the scenery in front of us and the road under our feet. We always think that happiness is ahead, in a distant place with a little light, and we are always attracted by its unreachableness. Therefore, we keep our eyes on the goal and move forward bravely. We think that we are brave, strong, optimistic, and hard-working, but we did not expect that happiness, this naughty child, might want to make a joke with us. When you are running, he is at your feet; when you are sweating, he is nearby; when you are tired and crying, he is behind you; silently, a hug, a greeting, a smile, a strange voice, and a knowing look. It turns out that he has always been with you. As long as you are willing, happiness will be by your side.
