Ancient Wizards: A Little Progress Every Day

[Not a wish-fulfillment novel + Western fantasy + Cynical/Cynical/Slow-paced + Character with a growth arc]
Having a progress system at the start is perfect! Dago is so eager to improve. The first thing he does every morning when he wakes up is look in the mirror and ask himself, "Have I improved today?" Especially as a wizard, if he improves by a tiny bit every day, after ten thousand sunrises and sunsets, he will surely reach the top of the world.
