Seeing as I write journal/blog style most of the time, I hadn't considered it for my comic writing, but it seems now like something I might consider. Harbin says that Kate Beaton had suggested diary writing to him. From what I gather it looks like a great way to practise developing a story, storyboard, and fleshing out humor from your every day.
I thoroughly enjoy Harbin's pencilling and his insight into depression from a working creative person's point of view (as opposed to just being creative). There are deadlines (mine are self-imposed, luckily, but I stick by them as best I can), and there are the things you do each day to cope (in Harbin's case, Kung Fu), but they don't "cure" the beast. I especially enjoyed his drawings on his relationships. It's a genuine perspective of "I'm a bit goofy, but hey, whatcha gonna do?" His adventures through NYC are congruent to the creative/working chaos in his head.
I have to see about ordering the rest of the set. TCAF really inspired me to push on with my comic and I look forward to reading more Dustin Harbin comics.
