格瓦拉第二次漫游南美前对母亲说
You can't go back home to your family, back home to your childhood, back home to romantic love, back home to a young man's dreams of glory and of fame, back home to exile, to escape to Europe and some foreign land, back home to lyricism, to singing just for singing's sake, back home to aestheticism, to one's youthful idea of 'art' and beauty, back home to the ivory tower, back home to places in the country, to the cottage in Bermuda, away from all the strife and conflict of the world, back home to the father you have lost and have been looking for, back home to someone who can help you, save you, ease the burden for you, back home to the old forms and systems of things which once seemed everlasting but which are changing all the time—back home to the escapes of Time and Memory.

The important thing is not to stop questioning. Curiosity has its own reason for existing.
