Books let you walk in the shoes of ANYONE. I would argue allowing yourself to open up and find life lessons in any book is an exceedingly valuable life skill for anyone, regardless of age or gender.
Grab a book, any book. Read it. There will be life lessons hidden in it if you allow yourself to think deeply on it after.
Murderbot Diaries. It's about a self-emancipated cyborg who tries to figure out who he is. Most are short novelas and the most recent 2 are novels. It deals a lot with understanding repressed emotions and reaching out to people when you've spent your whole life hiding.
It's also fun to watch Murderbot beat corporate ass. Also he tries hard not to actually hurt people and his name is self-ascribed and self-deprecating.
A man dies in 1988 and wakes back up as himself in the 60s, but with current memories.
I think people can probably take different things from this book, but one thing I got out of it was an appreciation for the fact that I very likely wouldn't have any of the things I treasure in life, had some of my tragedies not adjusted my course.
Even if you could go back and "do things right", you're a different person with all your future experiences. What if in trying to fix the past, you lost something you couldn't live without?
Stormlight Archive series starting with the way of kings
Many interesting perspectives but I think Dalinar’s character in the series would resonate with what you’re asking about.
Not that there aren’t many such views such as Kaladin and others with some insights into struggling with depression, feelings of inadequacy, weight of the world on you and fears of letting people down.
Insights into other perspectives
The Murderbot Diaries (already mentioned here and I can’t recommend it enough)
Klara and the Sun
written wholly from the perspective of a self aware machine and what it means to be a girls best friend, what it means to have purpose and how things change
Learning self acceptance or to appreciate how one fits into the world
The Rosie Project.
An interesting story written from the perspective of somebody who is neurodivergent but doesn’t realize they are.
I try to learn lessons from everything I read, but if I had to choose some that are tied to, like, emotional hurdles one may face during this period in their life, it'd still be difficult without knowing that person's ability to, uh, metaphoricize.
I know people who could learn a thing or two from The Very Hungry Caterpillar, and a few folks who need to read more nonfiction history.
I guess what you're really asking is "Are there any books from this particular point in your life from which you took special meaning?" And if that's the case, I'd have to say not really because everything I've read for the past decade or more has been to distract me from everything else.
I really like Hugh Howey, and I refuse to watch the Silo show based on his series because I don't want to tarnish the book series for myself. It is my Game of Thrones. As are the several spinoff novels from various authors - Michael Bunker being the most notable. Check out the Pennsylvania Omnibus.
Justin Cronin is another good author. His Passage series is pretty cool.
S.M. Reine if you're into YA angel/demon/werewolf stuff.
And of course Mr. Patrick Rothfuss, my doppelganger. I want so badly to recommend his Kingkiller Chronicles series, but he can't finish the third book. I love the first two almost as much as my first-born son, though.
If you can't learn a lesson from any of these, then you're not ready to be a manotaur.
