Praise the day in the evening.
Note: This popular proverb has been encapsulated in the English expression, "At the end of the day, ..." Do not be hasty to praise or even comment on an event, a life, or a period of time while it is in progress. It could change later and make you wrong.
Perhaps, Alexander Pope said it best. "Some praise at morning what they blame at night, But always think the last opinion right." An Essay on Criticism. 1711.
