I remember going to my grandmother's house to play in the winter vacation the year before last. One day my grandfather and I went to the market to buy food. Grandpa is a retired teacher. He is kind and humorous. It often makes me laugh. We talked and laughed all the way. There are so many vegetables in the market that vendors' cries of selling come and go. We came to a stall selling tofu and bought a piece of tofu. Grandpa said politely to the stall owner? Thank you? But the stall owner kept a cold face and said nothing. ? How can this stall owner have such an attitude? How can anyone do business like him? Did he leave the tofu stand because he was crazy? As we walked on, I asked my grandfather. ? He does this every day. ? Grandpa said. ? Then why are you so polite to him? I asked. Grandpa touched my head and answered with a smile? Son, life is alive, why should we let others decide our behavior? Why do you want to answer blows with blows, haggle over every ounce, and punish yourself with other people's mistakes? Remember, whether people are happy or not depends on themselves rather than others. ?

Now, it has been two years. Looking back now, what Grandpa said is really reasonable. Yes, we all have one in our hearts? The key to happiness. ? But we often leave it in the hands of others without knowing it. We will often hear such words in our lives. A wife complained:? I live a very unhappy life because the father of the child is often away on business. ? She put the key to happiness in her husband's hand. A teacher said:? The students in my class are undisciplined, do not pay attention to hygiene and do not study hard. Always causing trouble. This makes me fidget all day, and I am angry. ? He passed on the key to happiness to his students. An employee said:? The leader didn't appreciate me, and my talent was buried. Heroes are useless. ? The key to happiness was thrust into the boss's hand again. Many students bury three grievances all day:? Too much homework makes going to school too uncomfortable. I am bound by my teacher at school and supervised by my teacher when I go home. I am bored to death. ? I often hear some mother-in-law complain all day: the daughter-in-law is not filial, and her life is really bitter. ?

These people all made the same decision, that is, let others control their emotions. But once we give our emotions to others, we will feel that we are victims. Therefore, complaining and worrying have become our only choice. We began to blame others. And send a message:? My pain is caused by you, and you are responsible for my pain. ? This kind of person is moping all day, with a cold face, which makes others dislike approaching and even daunting.

A mature person often holds the key to his own happiness, and he doesn't expect others to make him happy. Instead, I often bring my happiness and happiness to people around me.

Students, where we live, no matter the environment, people, things and things, it is easy to play with our emotions. But no matter when and where, don't forget that it is often not others who dominate your destiny, but yourself. The key to happiness is always in your own hands.
