How it's used
This is a formal idiom often used in serious contexts like speeches, news reports, or when someone is making a solemn promise to change their behavior. It carries a heavy weight of sincerity and implies a complete transformation of character rather than just a minor adjustment. Because of this gravity, it sounds overly dramatic or stiff if used to describe trivial mistakes.
Examples
He decided to turn over a new leaf and stop gambling from now on.
Do you really want to repent and change your ways?

Common phrases

Common mistake
Learners often mistake this for a casual way to say sorry or change a habit. It is reserved for significant life changes or serious moral corrections, so using it for small things like being late or forgetting an item will sound sarcastic or unnatural.
