What is it called

That thing where you think of a string of words which are supposed to help life go more smoothly...

For example, one time I took a test for a restaurant job and did not score highly. I was asked to re-take it and think of the words "good customer service" to guide me to make better choices and improve the test outcome.

Next time there's an election day and people are deciding who to vote for or whether to even vote at all, maybe some can just think "relaxing airport experience" to give them some guidance.
