Is there anyone here who does/did practical design or repair work who has _NOT_ made a silly mistake?

I managed to feed 12V up a transputer link back in the day and killed a rather expensive processor as a result.

I disabled the over-current trip on a DEC H754 regulator brick in attempt to find why it was giving no output. The reason turned out to be the crowbar firing at the wrong time, without the overcurrent trip, the short provided by the crowbar blew transistors right off the board.

And many more..
