生来为了尝试

做所有我相信的事

按照我被教导的规则

更加了解我身边的事物

在爱的围栏中受到保护

你所见到的所有都是我

我真的相信

我生来为了尝试

我已经学习去爱

去了解

相信生活

但你不得不做出决定

对或错

有时你不得不牺牲自己喜欢的事情

但我生来为了尝试

说你原本应该成为什么，那没有意义

为已逝去的过去后悔，那也没有意义

生命充满了错误和命中注定

拨开乌云，看向更大的画面

你所见到的所有都是我

我真的相信

我生来为了尝试

我已经学习去爱

去了解

相信生活

但你不得不做出决定

对或错

有时你不得不牺牲自己喜欢的事情

但我生来为了尝试……
