Outside the window, the grass is in full bloom and the Yan language is whispering. It's another cherry red and green season. Looking up at the sky, bright blue sets off the sky. Once upon a time, I also naively fantasized about having the wings of two angels, flying freely and walking in the clouds. But, after all, how can I fly high? Beautiful fairy tales only belong to children's simple and brilliant desires. Time has already erased those childhood dreams, leaving only a vague and shallow shadow. I just remember what my parents said, study hard, make progress every day, and give up things that have nothing to do with the future. I study numbly every day, in order to keep my diploma alive. Am I happy? I often ask myself in the dead of night. I don't know, the answer is always these three words. Is this what I want? Become a puppet without joy, let the flood of society erode, then blend in, finally compromise and get lost in the endless abyss forever. What I want is nothing more than simple happiness, the desperate struggle for the ideal, the unrestrained crazy pursuit of the dream, as comfortable as a bird, without oppression or helplessness, just for the touch of passion in my heart. "Saint Zhuangzi daydreaming was bewitched by butterflies". I wonder whether the butterfly became Zhuangzi or Zhuangzi became a butterfly? Throughout the ages, perhaps he is the only one who has lived without fetters, indifferent to his own ambitions and forgetful. Zhuangzi, the only thing he has is thought, but that's enough. He is allowed to cross Wan Li freely. Suddenly, he understood that it was not the pressure of social survival that imprisoned him, but his own thoughts. The famous French philosopher once said that man's greatest strength lies in his thoughts. That is, I gave up my desire to fly. A lot of things suddenly became clear. We can't dominate the world, but we can control our own thoughts and realize our ideals. Why should we cling to the flight of the body, and why not let our thoughts have smart wings? Ideal is not a beautiful picture, but a blank sheet of paper, which needs us to outline and describe. Ideal is not a lush oasis, but a desert, which needs us to cultivate and cultivate. People can't go to heaven, but they can. Believe in yourself: when the sun goes down, I am the sun. Zhuangzi used his wisdom to tell us that we can fly if we want, and fly if we want. Yes, the sky is vast.
