Talking with writer P.A. Chawla helped me put a few things into perspective. I want to make a living with my words not be a starving artist. My children need to eat. I analyze options before I make decisions. Before making any major decision, I outline the main characters of the situation (story), review motivations and consider possible tension and plots. Because I want to make a living, I'm more likely to plan, organize and save before deciding to drop everything and write.
According to Chawla, I'm on to something. In a candid interview, writer P.A. Chawla shares her route to the Writing Life.
