Planning to end my 1 year reading slump. Looking for something meaningful to start again.

I have read a lot of fiction and fantasy absolutely avoided non fiction and self help for no reason.
After my year long reading slump I picked up some fiction and murder mysteries but lost intrest completely it feels exhausting and now I have this urge to read something real something about this world something to understand myself.

I'm open to narrative non fiction, historical
non fiction,self help anything really
But nothing too far apart from reality.
I don't know which of the self help or non fics are good because I never ventured into those waters

Going to a book festival this Saturday planning on picking up some books. All your recos would help me a lot.
Thanks
