For me the only time to finish artwork is late at night (weekends and weekdays) I go to bed around 3AM and wake up around 8AM Monday through Friday and fortunately I'm able to catch up on sleep during the weekends...but it takes a brutal toll. I drink a LOT of coffee and all that caffeine is sketchy at best. Sometimes it's all I can do to just get through the day. Still? When I'm "IN THE ZONE"-zoned out, GONE-just focusing on what I'm doing -it's like a ton of bricks kicked off my chest. I feel cleansed afterwards. I'm absolutely and flawlessly free and that time is all mine. It’s just me and just me and everything else disappears.
