As you know, I don't believe in fear, just an invention by men so they get all the money and good jobs.
I know of people who don't believe it, but depression is an illness, but unlike, say, a broken leg, you don't know when it'll get better.
I used to write in bed, starting when I woke up. I believe that creative work comes from our subconscious mind, so I try to keep the gap between sleep and writing as minimal as possible.
