I used to think jealousy was a bad thing. like a sin. and tried to avoid it. But jealousy is a wedding crasher. it shows up uninvited. Recently, I started using jealousy to my advantage. Jealousy is an incredible signal. it tells me -- at a very primal. no logic level, what my subconscious wants. it's a heat signal for my taste. I don't 'obey' the signal. But I observe it and it helps me now.
