Radio station KFKD broadcasts jealousy, according to Lamott, and it's one of the hardest things on the station to shut down.
If you keep writing, probably other writers who seem less deserving of success are going to do spectacularly well. It may be hard not to feel jealous if this happens.
Lamott describes in great detail how these kinds of scenarios play out. She reiterates that jealousy is an occupational hazard of being a writer, and she says that there are basically three things that help: 1) Getting older. 2) Talking about it until the fever breaks. 3) Using it as material.
It also helps if you can get someone to help you start chuckling about your jealousy.
