This extract of a poem by Stephen Fry, in his new book The Ode Less Travelled, seems especially fitting for information security practitioners:

How rare it is when things go right
When days go by without a slip
And don’t go wrong, as well they might.

The smallest triumphs cause delight –
The kitchen’s clean, the taps don’t drip,
How rare it is when things go right.

Your ice cream freezes overnight,
Your jellies set, your pancakes flip
And don’t go wrong, as well they might …
