求翻译：我很羡慕像你这样周游世界，但是我现在还年轻，生活要求我必须要努力工作，以后才能像你这样自由自在地周游世界。但是另一方面，30年以后我已经老了，到时再去周游世界，或许是另外一番心境了。是什么意思？

I admire him very much like you around the world, but I'm still young, life requires that I must work hard, can freely travel around the world like you in the future. But on the other hand, I already old after 30, then travel around the world at that time, perhaps a mood.
