Solitude turns self-awareness from theory into conversation.

Knowing about yourself in the abstract is different from encountering yourself. Reading and reflection give you concepts; time alone gives you the actual material, which is messier and more specific. Self-awareness only becomes usable when it stops being a theory about you and starts being a relationship with you.

Instead of reading more about how people work, spend an hour with your own actual thoughts and write down what is there. Not conclusions, just what you find. Repeated over weeks, that produces a kind of knowledge no amount of general understanding can supply.
