Psychology books to get to know who i am why i do what i do and how to be better at being me?

Hey y'all , I'm in my early twenties, I feel lost and unsure about who I really am. I don’t know what I stand for or what my principles are, and it’s tough to figure it all out on my own. I want to be better and become the person I dream of being—someone confident and secure in themselves. But without anyone in my life to help guide me, I’m turning to psychology books for answers.

I believe that understanding myself is the first step. I want to learn about my values, recognize my strengths, and identify my triggers and any bad habits that hold me back. Lately, I’ve been feeling bitter and frustrated, but I can’t quite figure out what I’m doing wrong. Sometimes i feel i dont even know the basics of anything.

I’m looking for books that can help me navigate different situations while staying true to who I am. I want to build better relationships without compromising my identity. Also please dont suggest motivational books, I have all the motivation in the world; I just need to find the right path to a happier life where I can feel secure in myself.
