Fiction: Self Discovery, Midlife Crisis, Etc

Greetings!

I’m looking for fiction where the main character deals with self discovery and/or a midlife crisis, or something along that line.

In my mind, the main character is a middle-aged working professional (career not important) that goes through some event/experience that brings about change in their life. Extra points if he/she ends up moving, changing careers, cuts people from their lives, etc.

For my interests, the main character would not be a minor/school aged student. A contemporary setting would be ideal, 1950s to present.

Thanks in advance!
