It takes a lot of time to be a good junkie or alcoholic - you spend hours getting the necessary supplies, then imbibing, then recovering, rinse and repeat. That's like eighteen hours of a day. And assuming you get out of that lifestyle before it macerates your heart, you have that Junkie Tunnel Vision, except now you get to use it for something positive: you know how to work tirelessly for one thing. Instead of using that tunnel vision to get high, I use it to make art.
Joshua MohrShamefulness is always a huge part of my characterizations. I like protagonists that reveal, either through "honesty" in their various thought processes or via their actions, perhaps telling us things they're not so keen on disclosing through their interactions with the outside world. Probably both during the duration of a novel.
