The best illustration of this problem is a sign I saw in front of a doughnut shop, which read: "The difference between an optimist and a pessimist is very subtle: the optimist sees a doughnut, while the pessimist sees a small hole in the middle of the doughnut." This short humorous remark reveals the essence of happiness. In fact, what people see with their eyes is often not the whole picture of things, but what they want to seek. Optimists and pessimists pursue different things, so they take two different attitudes towards the same thing.
One day, I stood in front of the counter of a jewelry store and put a package with some books beside it. When a well-dressed and handsome man came in and began to look at the jewels on the counter, I moved my bag politely, but the man looked at me angrily. He said he was an honest man and had no intention of stealing my bag. Feeling insulted, he slammed the door and walked out of the jewelry store. I am surprised that such an unintentional move should cause him to be so angry. Later, I learned that this man and I seem to live in two different worlds. In fact, the world is the same. The difference is that he and I have completely opposite views on things.
One morning a few days later, I woke up in a bad mood. I thought this day would be spent in a monotonous routine, and I felt how boring and boring the world was. When I was crowded in the dense traffic jam and slowly drove to the city center, I was full of resentment and thought: Why do so many idiots get driver's licenses? They drive too fast or too slow, and few people drive during rush hours. These people should have their driving licenses revoked. Later, I came to an intersection with a big truck at the same time, and I thought, "This guy is driving a big car, and he will definitely take it straight." But just then, the truck driver put his head out of the window, waved to me and gave me a cheerful and happy smile. When I drove away from the intersection, my anger suddenly disappeared completely and my mind was suddenly enlightened.
The truck driver's behavior made me feel like I was in another world. But in fact, the world remains the same, and the only difference is our attitude. Everyone will have similar episodes in life, and these episodes are the best way for us to pursue happiness. To live happily, you must first change your attitude. I think this is the true meaning of happiness.
