Yuliya, you look like a girl after my own heart--I love self-improvement books. If you do, you might enjoy Brian Johnson's website, optimize.me. What I love about this site is he provides excerpts in either video, podcast, or pdf formats for over 500 self-help books. I was in the habit for a while of "reading" a book a day. I learned so much. He has other motivational features on the website as well.
Check him out! Best self-help book I've read this year is Atomic Habits by James Clear.
