英文小作文：

Success is like a delicate flower, which blooms and then fades away, leaving only a fleeting memory behind. We all strive for success, but it often seems elusive and temporary, like the evanescent light of a firefly in the night. We may feel disappointed when our efforts are not rewarded with long-lasting success, but we should remember that it is not the end of the world. Instead, we should cherish the moments of temporary success and learn from our failures to become stronger and wiser. After all, success is not permanent, but it is fleeting and beautiful in its own way. We should embrace it with open arms and appreciate every moment of it, knowing that it will eventually fade away into the past, leaving only a beautiful memory behind.
