Rainer Maria Rilke

For it is not inertia alone that is responsible for human relationships repeating themselves from case to case, indescribably monotonous and unrenewed: it is shyness before any sort of new, unforeseeable experience with which one does not think oneself able to cope. But only someone who is ready for everything, who excludes nothing, not even the most enigmatical, will live the relation to another as something alive.
