以下是一篇英语励志小短文（约150字）及中文翻译，内容结合了要求中的经典段落，适合用于激励与自我成长：
Keep Your Heart Young
Whether you are sixty or sixteen, there is always a childlike curiosity within every human heart—a thirst for wonders and a joy in the game of life. Deep inside us, there exists an invisible "wireless station" that receives messages of hope, courage, and beauty from the world. As long as this station operates, youth remains eternal.
When tomorrow becomes today, and today fades into yesterday, we realize that time pushes us forward relentlessly. But growth is not an illusion; it is the truth of transformation. Face challenges with bravery, for fear is natural, yet overcoming it is heroic. Remember, the seeds of success lie hidden in every adversity.
（无论你年届花甲或正值青春，心中都应永葆孩童般的好奇——对奇迹的渴望与对生活的热爱。你我心底都有一座“无线电台”，接收世间传递的美好、希望与力量。只要它持续运转，青春便永不褪色。
当明天化为今日，今日褪为昨日，我们终被时间推着前行。但成长并非幻影，而是蜕变的真谛。勇敢迎接挑战吧，恐惧虽寻常，克服方显勇毅。请铭记：每一次挫折皆孕育着成功的种子。）
