I’d lean into whatever you’re interested in. As A Man Thinketh is a weekend read for me. Older stuff should be cheap or free. Biographies of people you admire.

Some people like stoicism and philosophy.

As a 20s finance nerd, I stuck to Think And Grow Rich.

As a currently depressed and burnout person, I’d probably go for biographies or Feeling Good by Dr. Burns and stuff like that.

I used to enjoy browsing a physical bookstore to pick what to read next. There’s a self help section.

The Power of Now and stuff like that mattered to me at a certain point, but doesn’t resonate with me now.
