i have two:
1. If the first resolution does not give results try once again
2. Errors are a source of experience
You could show a person rowing a lifeboat away from a sinking ship.
A person at a white board trying to add two simple numbers, with mistakes in the first two problems, but the right answer in the third problem. Cross out the two wrong answers.
You could do the same as above with a word that is misspelled the first two time.
