If jealousy and envy are patterns for you, then I would highly recommend looking into the enneagram. Many artists and creative types are the number 4 on the enneagram. The 4 also faces a lot of issues with envy. Just reading about the pattern, and learning to witness it as just that – a pattern – can liberate you in ways that you can’t imagine. The best book on the enneagram is The Wisdom of the Enneagram
by Don Riso and Russ Hudson. I can’t recommend this highly enough.
