What book(s) did you read that you wish you knew in your twenties?

Hey everyone!!

Just wanted to know what you think were some really great books and wish you had read earlier in life. It can be about finance, life, work, passion, IT, business, health or even like just good / interesting random things to know. I’m more interested in non fiction but I can welcome some fiction too! 🙂

FYI: I’m a female, who recently bought her first two books- The power of habit by Charles Duhigg and The courage to be disliked by Ichiro Kishimi. I study data science and so that’s something I like too, and I recently joined the workforce 🙂 I also like to read books about how to survive in a flood or how to survive in the wild 🤪
