阅读下面的材料，根据要求作文。真正的快乐是什么？是《悲惨世界》中冉阿让对芳汀女儿的真情呵护，是《红楼梦》中林黛玉葬花后的内心释然，是陆幼青在病魔控制下动人的键击声，是陈丽明伺候病危女儿时的轻轻叮咛，是徐虎在给居民清理下水道时的重重喘息，是李素丽在卖票时真诚的笑意……真正的快乐从哪来？人们都说当你在为自己既定的目标奋力前行，在挫折与痛苦的磨砺中，在忘我的追求时，她便悄然来临，真正的快乐无影无踪，来也如风去也如风，她可遏不可求，那些为追求快乐而“快乐”的人，恰恰不会求得真正的快乐，而那些对事业、工作、学习和生活全身心投入的人，常常会于不经意间，因真正快乐的光临而心旌摇荡，甚至手舞足蹈。你有相关的体验或见闻吗？请你根据以上内容自拟话题，写一篇不少于800字的作文，立意自定，标题自拟，文体自选。
