Some words of wisdom from Ray Bradbury from this interview. I highly recommend listening to the whole thing (it’s short), but the last portion deals with writing. The last question Mr. Bradbury is asked is whether he has any formal training in writing. He says no, and goes on to explain:
I am a dedicated madman, and that becomes its own training. If you can’t resist, if the typewriter is like candy to you, you train yourself for a lifetime. Every single day of your life, some wild new thing to be done. You write to please yourself. You write for the joy of writing. Then your public reads you and it begins to gather around your selling a potato peeler in an alley, you know. The enthusiasm, the joy itself draws me. So that means every day of my life I’ve written. When the joy stops, I’ll stop writing.
