The definition of sanity is when something doesn’t work, try something else.
And I think we can all agree that sanity is overrated.
That’s what I did when I was in IT. Users have a natural tendency to screw things up in unique and interesting ways. Troubleshooting often became a game of trying different solutions until one of them works.

My friend Rose had a problem with a scoring program for duplicate bridge (written by Sam.)
She asked both myself and a mutual friend Lionel for advice.

I found 1,000 things that don’t work.” –This and similar versions widely attributed to Edison though there appears to be no authoritative source
