The world breaks everyone and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure that it will kill you too but there will be no special hurry.
[Ernest Hemingway, A Farewell to Arms]

This is a poem by Jack Prelutsky, who was my childhood Shel Silverstein — his book The New Kid on the Block is the only poetry other than Ogden Nash that I read for many many years. I have a particular affinity for this poem because, to my chagrin, I often catch myself in the rough equivalent of the activity it describes. (I am, however, getting better at stopping.) Here goes:

I’ve got an incredible headache,
my temples are throbbing with pain,
it feels like a freight train with two locomotives
is chugging about in my brain.
I’m sure I can’t stand it much longer,
my skull’s being squeezed in a vise,
as regiments march to the blaring of trumpets,
and thousands of tap-dancing mice.

My head’s filled with horrible noises,
there’s a man mashing melons inside,
someone keeps drumming on bongos and plumbing,
as porpoises thrash in the tide.
An elephant herd is stampeding,
a volcano is blowing its top,
and if I keep hitting my head with this hammer,
I doubt that my headache will stop.
