" The old me knew. The old me cared. Fine, so far so good. Except that the old me cared so much that he actually got inside his own brain--my own brain--and locked off the bits that knew and cared, because if I knew and cared I wouldn't be able to do it. "

― Douglas Adams , The Hitchhiker's Guide to the Galaxy (Hitchhiker's Guide to the Galaxy, #1)
