Always be careful. Keep yourself with care.

The sky might fall, or you might fall yourself.

The earth might open suddenly. Beware.

Even if you are not a figure on a shelf,

There are other ways to break yourself to bits.

Get sleep enough, get love and music, get

Enough earth, air, and fire to keep your wits

Against more subtly threatening dangers yet:

Stars in their courses stumbling into dark

Above you; you yourself in silence held,

Or over-sleeping into death's long sleep.

Be careful always. Mark the seasons, mark

The hours, be curious, be one impelled

To live awake as long as the pulses leap.
