Rilke

Have patience with everything that remains unsolved in your heart. Try to love the questions themselves, like locked rooms, or books written in a foreign language. Do not now look for the answers. They cannot now be given to you, because you would not be able to live them. And the point is, to live everything. Live the questions now. Perhaps then, someday far in the future, you will gradually, without even noticing it, live your way into the answer.

 The engines won't turn and the train won't leave.
