Suggest me a book for somebody at a crossroads in their life

I am at a crossroads in life. I am not old, I have no major decisions to make. I am not financially comfortable but I am no longer impoverished. I have been sober from alcohol for over two years and now about a month sober from all substances.

This has resulted in me realizing: I’ve never known who or what I am. I’m 30, queer, and I’ve only ever enjoyed reading & writing. I am on a self discovery journey. It’s startling to realize I’m only 15 years younger than when one of parents died. Yet, I’ve never developed routines, coping mechanisms, discipline let alone hobbies. I want to learn who and what I am so I continue to grow, not just age. Then, once I know who & what I am, I can be me: fully and unapologetically.

The place I find myself is emotionally painful, yet it’s full of optimism. I am blessed with community yet feel very isolated.

So what books, fiction or nonfiction would you recommend to somebody at a crossroads in life or is seeking true self discovery?

Books I’ve read and loved within the last couple years:

Man’s Search for Meaning by Viktor Frankl

Meditations by Marcus Aurelius

Letters on the Shortness of Life by Seneca

Siddartha by Herman Hesse

Just Kids by Patti Smith

East of Eden & Grapes of Wrath by John Steinbeck

The Bell Jar by Sylvia Plath

I know why the caged bird sings by Maya Angelou

Nearly half of James Baldwin’s bibliography, favorites being Giovanni’s Room, Another Country, and The Fire Next Time.

Tl;DR: Books for self discovery or being at a crossroads, fiction or non fiction. See books above I’ve already read
