A famous politician once said, “To conquer the world, you must first conquer your own pessimism.” In life, pessimism envelops all stages of life, and it is inevitable during youth. Overcoming pessimism and dominating your life with cheerfulness and optimism will find life much more interesting. Pessimism is a ghost, and if you can conquer your pessimism, you can conquer all the difficult things in the world. It is impossible to live without pessimism, the important thing is to defeat it and conquer it. Life is not as good as it should be, and this is an objective law that cannot be transferred by human will. If you look at the unsatisfactory things as a novel or a drama that you conceived, you are a protagonist in that work, the mood will become much better. If you keep on sinking into the sorrow of the unsatisfactory, you will only make the unsatisfactory become more unsatisfactory. “Stay and go with no intention of watching the flowers bloom and fall in front of the courtyard; spoil and shame, follow the clouds in the sky.” Since pessimism is not helpful, why don’t we treat life with optimism and keep an optimistic state of mind? With an optimistic attitude towards life, you can see “flowers everywhere by the grass pond”, “a hundred birds singing in the spring mountains”, with a pessimistic attitude towards life, raising your eyes is only “yellow plum season rain”, lowering your eyebrows is to listen to “the wind”. If you look at life with a pessimistic attitude, you will only see “the rain at the time of the plum blossom” and listen to “the wind passing through the banana and the rain drops”. For example, if you open the window and look at the night sky, some people see a bright starry night sky; some people see a dark one. A person with a normal mindset can read the brightness of the stars in the vast night sky and enhance their confidence in life, a person with an abnormal mindset let the darkness bury itself and buried deeper and deeper. With an optimistic attitude toward life should be smiling, smile is optimism to defeat the most favorable weapon of pessimism. No matter how far life goes, do not forget to look at everything with their own smile. Smiling, life can conquer a lot of bad luck; smiling, life can be unfavorable to their own situation a little open. It is not easy to keep an optimistic state of mind, pessimism can be found everywhere in the ordinary day, while optimism requires effort and wisdom to keep yourself in a state of mind that is full of life everywhere. Pessimism makes the road of life narrower and narrower, optimism makes the road of life wider and wider, choose an optimistic attitude towards life is a kind of wisdom. In many helpless life, look up at the night sky to see the twinkling stars; look down at the earth, the earth is green and yellow, yellow and green beauty …… this optimism is the resilience of perseverance to support a landscape. Life where there is no scenery, the key depends on what kind of state of mind to maintain. Keeping an optimistic state of mind, “not to things, not to their own sadness”, we will be able to see all the scenery in the sky, “to see all the colors of spring on earth”.
