Self-growth book reccomendation

What genre would you typically read? I myself prefer fantasy/sci-fi. I can't say I read much non-fiction, but are there any particular non-fiction topics you are interested in too? I think it's always good to start somewhere or the options are limitless. Have you got any of your own recommendations? I have struggled to find a good book recently since stores are flooded with the likes of Colleen Hoover.

Honestly i have read one of her books and i have to say some scenes are concerning. But I think i will just read some biographies right now, and since im intersted in maths some books that reveal how each theory was discovered. I just wanted to expand my parameters and explore new genres
