Self-Awareness
The ability to evaluate one’s own ability is the most important skill of all. Without it, improvement is impossible.
This is kind of like Metacognition.
I must cultivate the ability to get out of my own head. Detachment is a sort of natural ego antidote. It’s easy to be infatuated with your own work. → i.e. every narcissist
What is rare nowadays is not raw talent, skill, or even confidence, but humility, diligence, and self-awareness.
