turns over a new leaf

Starts behaving better

To turn over a new leaf is to make a fresh start by changing one's behavior or habits for the better.

The leaf is a page in a book—turning to a blank page suggests beginning anew: After years of reckless spending, she turned over a new leaf and started saving.

Often used with resolutions or reform after a period of poor conduct.
