I'm a fairly ascetic person. And I do most of my writing at night. You don't get distracted, your brain goes into what you are writing about, into the world you're writing about, rather than into the world you're in. ↗
I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... such emotions make a man forget food, sleep, friends, love, everything. ↗
