Novel About Regular People Finding Happiness

I'd like an ultimately uplifting book about regular or quirky characters overcoming difficulties to find contentment, maybe even happiness. Here are some books I've read recently that I consider like this:

The Maid by Nita Prose

The Sideways Life of Denny Voss by Holly Kennedy

The Collected Lives of Chuck Burke by Shawn Inmon

How to Age Disgracefully by Clare Pooley

Eleanor Oliphant Is Completely Fine by Gail Honeyman
