The Guardian has a fun test that will provide you with a poem suitable for your mood. Go here and take it. I did, the results follow:
You're experiencing a bit of an existential crisis, aren't you? Here's a poem to help you through your long dark night of the soul.
No matter what I say,
All that I really love Is the rain that flattens on the bay,
And the eel-grass in the cove;
The jingle-shells that lie on the beach
At the tide-line, and the trace
Of higher tides along the beach:
Nothing in this place.
Edna St. Vincent Millay (1892 - 1950)
