Let me put it this way: I don't plan to retire. What would I do, become a brain surgeon? I mean, a brain surgeon can retire and write novels, but a novelist can't retire and do brain surgery - or at least he better not.
I tell public audiences, don't go to a podiatrist for brain surgery; don't go to an astronomer for planetary science.
I wanted to be a writer, but at the time, I spent my days working a retail job, my nights sleeping in my childhood bedroom, and while I had written short stories here and there, I didn't know how to write good fiction anymore than I knew how to perform good brain surgery.
If someone suddenly lost their director the day before shooting and wanted me to step in, I'd be willing to. But I'd do brain surgery the same way. I'm always up for something new.
A close friend of mine's daughter was diagnosed with Epilepsy and battled seizures her first 2 years so this cause hits close to home. She ended up having brain surgery and has been seizure-free since. It really is an incredible story. Anything I can do to help promote Epilepsy awareness, I am with it.
